Question

According to Ohm's law, the electric current I, in
amperes, in a circuit varies directly as the voltage V.
When 14 volts are applied, the current is 2 amperes.
What is the current when 29 volts are applied?

Answer 1

Answer:

4 ampers

Step-by-step explanation:

WHEN 12 VOLTS ARE APPLIED, THE CURRENT IS 4 AMPERES.

Answer 2

The current when 29 volts are applied is; 4.14 amperes.

According to the question;

The electric current I, in amperes, in a circuit varies directly as the voltage V.

In essence;

I/V = constant.

Therefore;

I1/V1 = I2/V2

where;

• I1 = 2amperes

• V1 = 14volts

• I2 = ?

• V2 = 29

Therefore; we have;

• 2/14 = I2/29

By cross product;

• 14 × I2 = 29 × 2

• I2 = 58/14

I2 = 4.14 amperes.

In conclusion, the current when 29V voltage is applied is; 4.14 amperes.
