Ohms

Question 1

What are voltage, current and resistance?

Answer 1

Voltage: amount of “push” the electrons have.

Current: amount of charge passing one point in the circuit in 1 second.

Resistance: relative slow down of electrons around the circuit

Question 2

What happens as voltage increases and decreases?

Answer 2

As voltage increases, what happens to the current?

INCREASES

If we increase resistance, what happens to the current?

DECREASES

Question 3

What is Ohms Law?

Answer 3

Ohm’s Law say that the electric current through a conductor between two points is directly proportional to the voltage across the two points.

You use the V,I, R triangle for calculations.

These are the formulas

V=IxR
R=V/I
I=V/R

Question 4

What is the Grass Method?

Answer 4

G = Given
R = Required
A = Analysis
S = Solution
S = Statement
