What is the potential difference across the 40 ΩΩ resistor? Express your answer with the appropriate units.

26volts

Explanation:

The question is incomplete. Here is the complete question

Suppose that E = 65 V.

What is the potential difference across the 40 Ω resistor? Express your answer with the appropriate units.

Using ohms law;

V = IR

V is the potential difference

I is the current

R is the resistance

First is to get the current in the 40Ω resistor

Since the resistors are connected I'm series, same current will flow in them.

Using:

I = E/Rt

Rt = 40+60

Rt = 100Ω

I = 65/100

I = 0.65A

Hence the current in 40Ω resistor is 0.65A

Next is to calculate the potential difference V across the 40Ω resistor

V = IR

V = 0.65(40)

V = 26Volts

Hence the potential difference across the 40Ω resistor is 26volts
