Question

You have just run a cable from your home electrical panel to a small shed behind your house, a distance of about 15 feet. After performing a test on the cable, you find that the voltage drop from one end to the other is about 10% What can you do to reduce the resistance in the connection? a. Use a cable with wires that have a larger diameter. b. Use a cable with wires that have a smaller diameter. c. Use a longer cable. d. Nothing-10% voltage drop is normal. Resistance in a circuit always produces heat a spark electrical arcing c. increased conductivity

Explanation / Answer

1.In cables power trasmission the resistance of cable is inversly propositional to length of the cable.

So here inoreder to reduce the resistance value the length of the cable will increaes.

2.resistance in circuit always produces heat.

heat = i2Rt

here i = current through resistor

R -resistance value

t = time taken
