what is the formula of resistance and equivalent resistance
Answers
Answer:
The total resistance of the circuit is found by simply adding up the resistance values of the individual resistors: equivalent resistance of resistors in series : R = R1 + R2 + R3 + ... A series circuit is shown in the diagram above. The current flows through each resistor in turn.
Answer:
The formulas of resistance are as follows:-
- By Ohm's law, R = V ÷ I
- R = rho * l/A
Resistance is a property that resist the flow of electrons in a conductor.
It helps in controlling the magnitude of the current.
The SI unit of resistance is ohm.
The formula for equivalent resistance is as follows:-
- Series connection - Rs = R1 + R2 +.....+ Rn
- Parallel connection - 1/Rp = 1/R1 + 1/R2 +....+ 1/Rn
The series connection and parallel connection are two ways in which resistors can be connected.
The equivalent resistance in series connection is the maximum value of resistance in a circuit.
The equivalent resistance in parallel connection is the minimum value of resistance in a circuit.
