Answer 8

is a measure of how difficult it is for an electric current to flow in a material.

Question 9

is the amount of energy a source uses to move one coulomb of electrons through the circuit.

Answer 9

Voltage

Question 10

Ohm’s law

Answer 10

is a mathematical equation that describes the relationship among voltage, current and resistance.

Question 11

math

Answer 11

V=IR

Current=I, resistance=R,V=voltage

Voltage is measured in Volts (V)

I is measured in amperes (A)

R is measured in ohms( 𝛀)
