Question 5

Describe ohm’s law

Answer 5

Current is directly proportional to voltage and is inversely proportional to resistance
I = E/R

Question 6

Describe the 2 ways that Kirchoff’s voltage law can be expressed

Answer 6

1. The voltage rises in a circuit are equal to the voltage drops.In that circuit
2. The algebraic sum of the voltages in a closed-loop equals 0
