What kind of charging occurs when you slide your body across a plastic surface?
Electrostatics: When a person slides across a plastic surface, the plastic produces a net negative charge and your body surface a net positive charge.
What will happen if you switch the battery so that the positive end is on the right quizlet?
electromagnet. What will happen if you switch the battery so that the positive end is on the right? The compass will switch directions.
Which end of the battery is the positive terminal?
Most battery cases are marked positive (+) on one end and negative (–) on the other. These markings indicate the positive and negative battery terminals. The direction of the electric current in a closed circuit is from the negative (–) terminal of the battery to the positive (+) terminal of the battery.
How much energy is given to each Coulomb of charge that flows through a 1.5 V battery?
How much energy is given to each coulomb of charge that flows through a 1.5-volt battery? 1.5 Joules.
In what direction is the conventional current flowing through the circuit recall that current is the flow of positive charge?
In what direction is the (conventional) current flowing through the circuit? Recall that current is the flow of positive charge. The current flows from the positive terminal, through the wires and resistor, and into the negative terminal. Use the noncontact ammeter to measure the current flowing through the circuit.
What is the direction of the conventional current?
The flow of electrons is termed electron current. Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative.
In what direction is the conventional current flowing through the circuit?
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Which terminal of the battery has a higher potential quizlet?
The positive terminal has a higher potential than the negative terminal (recall that the voltmeter measures the potential difference between the red probe and the black probe).
When a battery rating is given in amp hours what quantity is it trying to tell you?
What quantity is measured by a battery rating given in ampere-hours (A x h)? Ampere hours measures charge. The ampere is a charge per unit of time, and the hour is a time, so the product is a charge.
When an electric cell is connected to a circuit?
When an electric cell is connected to a circuit, electrons flow away from the negative terminal in the circuit. But within the cell, electrons flow to the negative terminal. Explain. In the circuit, the electrons flow from the negative terminal (high PE) to the positive terminal (low PE).
What are two ways to increase the resistance in a wire?
length – longer wires have greater resistance. thickness – smaller diameter wires have greater resistance. temperature – heating a wire increases its resistance.
How does changing the length of wire affect the resistance?
First, the total length of the wires will affect the amount of resistance. The longer the wire, the more resistance that there will be. Wider wires have a greater cross-sectional area. Water will flow through a wider pipe at a higher rate than it will flow through a narrow pipe.
