What do u mean by equivalent resistance?
The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. Essentially, the circuit is designed either in Series or Parallel. Electrical resistance shows how much energy one needs when you move the charges/current through your devices.
What is the effective resistance between A and B?
therefore the effective resistance between A and B is 10Ω
What is the effective resistance in series and parallel?
The effective resistance in series combination of two equal resistance is ′s′. When they are joined in parallel the total resistance is p. If s=np then the minimum possible value of ′n′ is.
What happens to the effective resistance when two or more resistors are connected in parallel?
When resistors are connected in parallel, more current flows from the source than would flow for any of them individually, so the total resistance is lower. Each resistor in parallel has the same full voltage of the source applied to it, but divide the total current amongst them.
Which of the following is the same in parallel connection of resistance?
correct answer is : Potential difference is the same in parallel connection of resistances.
How do you find resistance with only voltage?
Ohms Law and Power
- To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
- To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
- To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
- To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)
Is the current the same in a series circuit?
The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. If the circuit is broken at any point, no current will flow.
Which circuit has greatest resistance?
series circuits
