ICSE Class 10 Physics Electro motive Force, Potential Difference and Resistance

Solution

When resistors are connected in parallel, the potential difference across each resistor is the same and the current across each resistor is different.

Solution

When resistors R1 and R2 are connected in parallel, the resultant resistance (R) is.

1/R = 1/R1 + 1/R2

1/R = (R1 + R2)/(R1 x R2)

R = (R1 x R2)/(R1 + R2)

Solution

When three resistors R1, R2 and R3 are connected in parallel, the total current flowing through the circuit is I1 + I2 + I3.
