Not yet answered Marked out of 1.00 P Flag question Answer: Question 3 V1 3.0 V, V2 18.0 V, R 8.00, R2 21.0 m. What is the voltage drop across the 21.0 resistor? Not yet answered Marked out of 1.00 P Flag question Answer:

Explanation / Answer

The equivalent value of battery emf is V=V1+V2=33 V

The equivalent value of resistance is R=R1+R2= 70 Ohm

Thus, the current in the circuit is i=V/R=33/70= 0.47 A.

The rate of heat that dissipated through 52 Ohm is

P=i^2R=(0.47)2(52)=11.6 W
