Deck 2: Electrical Measurements and Ohms Law

Question 1

P = Volts x Amps.

Answer 1

True

Question 2

Write Ohm's Law as a formula using the symbol R for resistance, I for current, and V for volts.

Answer 2

I = V / R
V = I x R
R = V / I

Question 3

What does electron flow theory state?

Answer 3

Current consists of electrons that flow from a negative potential toward a positive potential.

Question 4

________________ is the force that pushes the current through a conductor.

Question 5

"Ground" is a motor, light, or any electrical appliance in a circuit.

Question 6

Power ______________ is the ratio of output power to input power.

Question 7

Open circuits occur when conductive parts of wires or components touch.

Question 8

List three common power sources.

Question 9

The ohm is a measure of resistance.

Question 10

Conventional flow theory states that current flows from the most positive point to the most negative point in a circuit.

Question 11

What can cause open circuits?

Question 12

In a circuit, opposition to current flow is called ___________________.

Question 13

What do watts measure?

Question 14

Directed electron flow occurs when a(n) _________________ is placed in the circuit.

Question 15

__________________ is a proportion that shows how voltage, current, and resistance are related in a circuit.
