Question

A resistance of 6 ohm is connected in series with another resistance of 4 ohm. A potential difference of 20 volt is applied across the combination. Calculate the current through the circuit and potential difference across the 6 ohm resistance.​

Answer 1

Answer:

i = 2A V (6 ohm resistor) = 12 V

Explanation:

Since the resistors are connected in series,

R(total) = 6 + 4 = 10 ohms

We know that V = IR

=> I = V/R

.°. I = 20÷10 = 2A

And, since V = IR,

Pd across the 6 ohm resistor will be,

V = 2 A × 6 ohms = 12 V
