Chapter 3

Question 1

Calculate voltage, amperage, and resistance using Ohm’s Law

Answer 1

E = I x R
Volts = Amps x Ohms

Question 2

E

Answer 2

Electromotive Force (Voltage)
E = I x R

Question 3

I

Answer 3

Intensity of Current (Amperage)

I = E / R

Question 4

R

Answer 4

Resistance (Ohms)

R = E / I

Question 5

Calculate wattage, voltage and amperage using the power formula

Answer 5

P = I x E
Watts = Amps x Volts

Question 6

P

Answer 6

Watts

P = I x E

Question 7

I

Answer 7

Amperage

I = P / E

Question 8

E

Answer 8

Voltage

E = P / I
