Question

Решите по ,используя теорему ома 5. solve these problems: 1. how much is the current in the circuit if a 60-volt source is connected to a resistance of 1,600 ohms? 2. how much is the voltage in a circuit having a current equal to 25 amp, if a 25-ohm resistance is connected to it? 3. a 70.35-ohm resistance is connected to the circuit. how much is the voltage if the current equals 4.5 amp?

Answer 1

1. I=60/1600=0,0375 amp. The current in the circuit is 0,0375 amp.
2. U=25*25=625 volt. The voltage in the curcuit is 625 volt.
3. U=70,35*4,5=316,575 volt. The voltage in the curcuit is 316,575 volt.
