Answer to Question #209860 in Electric Circuits for Tiger

Question

A 36 ohm resistor and an 18 ohm resistor are connected in series across a 15V battery. What is the voltage across a) the 36 ohm resistor. b) the 18 ohm resistor?

Answer 1

Gives

$R_1=36\Omega,R_2=18\Omega$

V=15V

Both resistance are series combination

$R_{net}=R_1+R_2$

$R_{net}=36+18=54\Omega$

$I_{net}=\frac{V}{R}=\frac{ 15}{54}$

$I_{net}=0.277A$

$V_1=IR_1=0.277\times36=9.972V$

$$V_2=IR_2=0.277\times18=4.986V$$
