Question
The resistance R3 = 10.0 ?, R2 = 30.0 ? and R1 = 20.0 ?. The battery supplies 18.0 V. Assume that the battery has no internal resistance.
What is the current following through R3?
What is the current following through R2?
What is the current following through R1?
What is the current following out of the battery?
What is the voltage across the resistor R2?
Explanation / Answer
Current through R3= Voltage applied across it/Resistance=18V/10 ohms =1.8A
Current through R2=Voltage applied across it/Resistance=18/30=0.6 A
Current through R1=Voltage applied across it/Resistance=18/20=0.9 A
toal current drawn =0.9+0.6+1.8=3.3 A
