Calculating Voltage in an Electric Circuit

To calculate the voltage in an electric circuit, you can use Ohm's law, which states that the voltage (V) is equal to the current (I) multiplied by the resistance (R). The formula is:

V = I * R

Where: - V = Voltage (in volts) - I = Current (in amperes) - R = Resistance (in ohms)

Given: - Current (I) = 0.9 mA (milliamperes) = 0.9 * 10^-3 A - Resistance (R) = 2 ohms

Using the formula, we can calculate the voltage:

V = 0.9 * 10^-3 A * 2 ohms

V = 0.0018 volts

Therefore, the voltage in the electric circuit is 0.0018 volts.
