Answer:
26volts
Step-by-step 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
