Question

Use the information in the table about four different electric circuits to answer the question
Which circuit will have the greatest electric current?

circuit 4
circuit 3
circuit 1
circuit 2

Answer 1

Answer:

Circuit 4

Explanation:

To know the correct answer to the question given above, we shall determine the current in each circuit. This can be obtained as follow:

For circuit 1:

Resistance (R) = 0.5 ohms

Voltage (V) = 20 V

Current (I) =?

V = IR

20 = I × 0.5

Divide both side by 0.5

I = 20 / 0.5

I = 40 A

For circuit 2:

Resistance (R) = 0.5 ohms

Voltage (V) = 40 V

Current (I) =?

V = IR

40 = I × 0.5

Divide both side by 0.5

I = 40 / 0.5

I = 80 A

For circuit 3:

Resistance (R) = 0.25 ohms

Voltage (V) = 40 V

Current (I) =?

V = IR

40 = I × 0.25

Divide both side by 0.25

I = 40 / 0.25

I = 160 A

For circuit 4:

Resistance (R) = 0.25 ohms

Voltage (V) = 60 V

Current (I) =?

V = IR

60 = I × 0.25

Divide both side by 0.25

I = 60 / 0.25

I = 240 A

SUMMARY

Circuit >>>>>> Current

1 >>>>>>>>>>> 40 A

2 >>>>>>>>>>> 80 A

3 >>>>>>>>>>> 160 A

4 >>>>>>>>>>> 240 A

From the above calculation, circuit 4 has the greatest electric current.

Answer 2

To know the right answer to the question given above, we shall estimate the currents in each circuit. This can be obtained as below.

• The table has four circuits with varying resistance and voltages. The circuit four has the highest and circuit one has the lowest voltage.

• The circuit 1:  Resistance (R) = 0.5 ohms

• , Voltage (V) = 20 V

• Current (I) =?

• , V = IR  20 = I × 0.5

• Divide both side by 0.5   I = 20 / 0.5   I = 40 A
