Electrical Potential Difference

Question 1

Kirchoff’s Voltage Law

Answer 1

In a closed circuit loop (a circuit which current flows in a loop, uninterrupted), the total potential gain must equal the total potential drop . The sum of energy inputs (voltage from battery) must equal the sum of the energy outputs from loads in a closed circuit loop.

Therefore Vtotal = V1+V2+…Vn

Two equations always - q=ne v=w/q

-often need to convert between n and q
