Question

A circuit is built based on the circuit diagram shown.

Answer 1

Answer : Current in 50 ohms resistor is 1.2 A.

Explanation :

It is given that,

Voltage, $V=60\ V$

In the given figure, all three resistors i.e. 40 ohms, 50 ohms and 30 ohms are in parallel combination.

We know that in parallel combination, the voltage in all resistor remains the same.

From Ohm's law :

V = I R

V = voltage

I = current

R = resistors

So, the current in 50 ohm resistor will be :

$I=\dfrac{V}{R}$

$I=\dfrac{60\ V}{50\ \Omega}$

$I=1.2\ A$

So, the current flowing in 50 ohms resistor is 1.2 A.
