Question

Calculate the voltage (in volts) of a solar cell that generates a current of 139 milliamps and has a resistance of 6 ohms.

Answer 1

The voltage of a solar cell is 0.834 Volt

Step-by-step explanation:

Given that,

Current = 139 milli amps

Resistance = 6 ohms

We need to calculate the voltage of a solar cell

Using ohm's law

`V = IR`

Where, I = current

R = resistance

V = voltage

Put the value into the formula

`V=0.139*6`

`V=0.834\ V`

Hence, The voltage of a solar cell is 0.834 Volt

Answer 2

834 milli-volts

Step-by-step explanation:

Data provided in the question:

Current = 139 milliamps = 139 × 10⁻³ A

resistance = 6 ohms

Now,

The relation between the current , resistance and voltage is given as:

Voltage = Current × Resistance

on substituting the respective values, we get

Voltage = 139 × 10⁻³ × 6

or

Voltage = 834 milli-volts
