The formula to calculate the Voltage from Impedance (E) is:
\[ \text{E} = \text{Z} \times \text{I} \]
Where:
Voltage from impedance refers to the voltage drop across a component or circuit that has a certain impedance when a specific current flows through it. Impedance is the measure of opposition that a circuit presents to the passage of a current when a voltage is applied. It is a combination of resistance and reactance and is measured in ohms (Ω).
Let's assume the following values:
Using the formula to calculate the Voltage:
\[ \text{E} = 10 \times 2 = 20 \text{ volts} \]
The Voltage is 20 volts.
