Resistors of 10 and 30 ohms are connected in series to a 120-V source. What is the current l owing in the 30 ohm resistor

the current through 30 ohms resistor is 30 A.

Explanation:

Given;

resistor, R₁ = 10 ohms

resistor, R₂ = 30 ohms

voltage of the source = 120 V

The effective resistance, Rt = 30 ohms + 10 ohms = 40 ohms

The current through 30 ohms resistor is the same as the current through 10 ohms resistor because they are connected in series.

Appy ohms law to determine the currecnt through 30 ohms resistor;

I = V / Rt

I = 120 / 40

I = 3 A

Therefore, the current through 30 ohms resistor is 30 A.
