Question

What is the potential Across R1 = 14ohms resistor in the figure....

What is the potential Across R1 = 14ohms resistor in the figure.... Part A What is the potential difference across the R1 = 1 4? resistor in the figure (Figure 1) if R = 24 ohm? Express your answer to two significant figures and include the appropriate units. Part B What is the potential difference across the R2 = 24 ohm resistor in the figure if R1 = 14 ohm? Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

A)

Here, E = 15 V

Now , for potential across R1 = 14 ohm

Using Potential divider ,

V(R1) = 14 * 15/(14 + 24)

V(R1) = 5.53 V

the potential across the R1 is 5.53 V

B)

Now ,

V(R2) = E - V(R1)

V(R2) = 15 - 5.53

V(R2) = 9.47 V

the potential across R2 is 9.47 V
