Dynamic electricity

Question 1

What is the current intensity?

Answer 1

Current Intensity: It is the number of charges passing through a given point in an
the electrical circuit in one second.

Question 2

How is an ammeter connected within a circuit

Answer 2

In series
Positive terminal on Ammeter to positive terminal on power supply.
Negative terminal on Ammeter to negative terminal on power supply.

Question 3

what is the potential difference?

Answer 3

Potential Difference: It is the amount of energy transferred between two points in an
electrical circuit.

Question 4

How a Voltmeter should be connected within a circuit:

Answer 4

in parallel

Positive terminal on Ammeter to positive terminal on power supply.
Negative terminal on Ammeter to negative terminal on power supply.

Question 5

How a Voltmeter should be connected within a circuit:

Answer 5

in parallel

Positive terminal on Ammeter to positive terminal on power supply.
Negative terminal on Ammeter to negative terminal on the power supply.

Question 6

What is resistance?

Answer 6

Resistance: It is the ability of a material to limit the flow of electrons in an electrical
circuit.

Question 7

A refrigerator is connected to 120 V outlet and has a current intensity of 150A going through
it. What is the power of this refrigerator.

Answer 7

18000w

Question 8

(est) Kirchoffs law for series

Answer 8

I total = I 1 = I 2 = I 3 = I 4
V total = V 1 + V 2 + V 3
R eq = R 1 + R 2 + R 3

Question 9

(est) kirchoffs law for parallel

Answer 9

I total = I 1 + I 2 + I 3
V total = V 1 = V 2 = V 3
R eq = 1 + 1 + 1
R 1 R 2 R 3
