(a) Find the equivalent resistance between points a and b in Figure P18.7. (b) Calculate the current in each resistor if a potential difference of 34.0 V is applied between points a and b. Figure P18.7

(a)

To determine
The equivalent resistance between the point a and b in the given figure P18.7.

Explanation

Given Info: The two parallel resistors is  R1P=7.00Ω and R2P=10.0Ω .

Explanation:

The two parallel resistors is R1P=7.00Ω and R2P=10.0Ω .

Formula to calculate the equivalent resistance of the two parallel resistors is,

1RP=1R1P+1R2P

• RP is the equivalent resistance ,
• R1P and R2P is the two parallel resistors,

Rewrite the above relation as RP .

RP=R1PR2PR1P+R2P

Substitute 7.00Ω for R1P and 10.0Ω for R2P .

RP=(7

(b)

To determine
The current through each resistor from the given figure P18.7.
