When one of three parallel resistors is removed from a circuit and then the total current in the circuit?

Parallel Combination of Resistors: A parallel combination of resistors with the source voltage is the circuit in which all the resistors gets the voltage of the battery, and therefore, the total current drawn from the battery equals the sum of the current through each resistor in parallel.

Can a resistor burn out?

Burning of Resistor When a resistor has been overloaded with voltage exceeding its power rating, the resistor will become very hot to touch, darken considerably and possibly even melt or catch on fire. Although a resistor may appear damaged at this point, it can still be functioning.

How do you know if a circuit is shorted?

A short circuit occurs when an accidental connection is created between a neutral wire or the ground in a circuit. If you notice fuses being repeatedly blown or a circuit breaker trips frequently, it could be a sign of a short circuit. You may also hear loud, popping noises when the circuit is activated.

What causes resistors to fail?

A fixed composition resistor normally fails in an open configuration when overheated or overly stressed due to shock or vibration. Excessive humidity may cause an increase in resistance. A variable composition resistor may wear after extensive use, and worn away particles may cause high resistance short circuits.

Can you bypass a ballast resistor?

The duty of the ballast resistor is to limit voltage to the ignition coil. A quick and easy way to diagnose ballast resistor failure is to bypass it by running a temporary jumper wire from the battery to the coil. If it starts and remains running, you’ve found the problem.

Will a blower motor work without the resistor?

Power to the blower motor is fed through the blower motor resistor, so if it fails or has any issues power can be cut off to the motor. A blower motor without power will not be able to produce any air pressure, and as a result the heating and air conditioning system will be left with no air coming from the vents.
