Question

Jerry has approached you with a series circuit problem. He's trying to figure out the electricity for a new circuit in his house. He needs to find the total resistance. Which equation
should Jerry use?

A. R=R, + R, + Rn
B. R=Ri* Ra* Ra
C. R = 1/R, * Ra* Rn
D. R= 1/R, + 1/R2+ 1/Rn

Answer 1

Answer:

R=v^2/p

Explanation:

The Ohm's law is a relation between voltage, current and resistance:

If you dont know the current and know the power circulating in the circuit, you can use the relation between power, voltage and resistance:

R=v^2/p
