__Source Voltage Formula:__

Source voltage is a fundamental parameter in circuit analysis, particularly when dealing with series circuits involving batteries and other voltage-dropping components like resistors or diodes.

It represents the total voltage that must be applied to a circuit to overcome the voltage drop across the circuit components and deliver the required driving voltage at a certain point.Top of Form

This formula helps in determining the necessary input voltage to ensure the proper function of the circuit under given conditions.

Source voltage, V_{s(V)} in volts equals the sum of the product of resistance, R_{(Ω)} in ohms and current, I_{(A)} in amperes, plus the driving voltage, V_{d(V)} in volts.

Source voltage, V_{s(V)} = R_{(Ω)} * I_{(A)} + V_{d(V)}

V_{s(V)} = source voltage in volts, V.

R_{(Ω)} = resistance in ohms, Ω.

I_{(A)} = current in amperes, A.

V_{d(V)} = driving voltage in volts, V.

**Calculate the source voltage required to ensure a driving voltage of 9 volts across a device with a total resistance of 2 ohms, when the current flowing is 3 amperes:**

Given: R_{(Ω)} = 2 Ω, I_{(A)} = 3A, V_{d(V)} = 9V.

Source voltage, V_{s(V)} = R_{(Ω)} * I_{(A)} + V_{d(V)}

V_{s(V)} = 2 * 3 + 9

V_{s(V)} = 6 + 9

V_{s(V)} = 15V.

**Determine the current needed for a circuit with a resistance of 4 ohms and a driving voltage of 5 volts, if the source voltage is 11V:**

Given: R_{(Ω)} = 4Ω, V_{s(V)} = 11V, V_{d(V)} = 5V.

Source voltage, V_{s(V)} = R_{(Ω)} * I_{(A)} + V_{d(V)}

I_{(A)} = V_{s(V)} – V_{d(V)} / R_{(Ω)}

I_{(A)} = 11 – 5 / 4

I_{(A)} = 1.5A.
