Charge, Electricity, And Circuits
Basically, the act of moving or revolving around as in a circle or orbit is what defines a circuit. In electricity, a circuit is an enclosed path of an electric current and it’s usually designed for a particular function. The quiz below on charge, electricity, and circuits will broaden your understanding. Give it a try!
- 1.A circuit has three resistors of 2 O, 6 O, and 10 O in series with a 3 V battery.A. What is the equivalent resistance?B. What is the current in the circuit?C. How much power is used by the circuit?D. How much energy is used by the circuit in 10 minutes?
- 2.What is the standard electric potential delivered in household circuits?
- A.
