## Applied Voltage Formula:

Applied voltage is a vital concept in electrical circuits, especially when analyzing the voltage required to overcome the resistance in a circuit to maintain a certain current level.

It directly determines how much voltage is needed for specific components to function as intended under normal operating conditions.

This calculation is crucial in ensuring that the necessary voltage is supplied for optimal operation of electrical devices and systems.

It helps in designing circuits, selecting appropriate components, and ensuring energy efficiency and safety in electrical applications.

Applied voltage, Va(V) in volts equals the product of the actual current, Ac(A) in amperes and the resistance, R(Ω) in ohms through which it flows.

Applied voltage, Va(V) = Ac(A) * R(Ω)

Va(V) = applied voltage in volts, V.

Ac(A) = actual current in amperes, A.

R(Ω) = resistance in ohms, Ω.

### Applied Voltage Calculation:

1. Calculate the applied voltage required to maintain a current of 3 amperes through a resistor of 4 ohms:

Given: Ac(A) = 3A, R(Ω) = 4 Ω.

Applied voltage, Va(V) = Ac(A) * R(Ω)

Va(V) = 3 * 4

Va(V) = 12V.

1. The applied voltage to be 12V with a current of 3 amperes, find the resistance.

Given: Ac(A) = 3A, Va(V) = 10V.

Applied voltage, Va(V) = Ac(A) * R(Ω)

R(Ω) = Va(V) / Ac(A)

R(Ω) = 10 / 3

R(Ω) = 3.3 Ω.

### Applications and Considerations:

• Circuit Design: Calculations of applied voltage are essential for designing circuits that need to handle specific currents through various resistive elements.
• Component Selection: Understanding the applied voltage aids in selecting the correct components that can withstand the electrical loads expected in the circuit.
• Energy Efficiency: By calculating the applied voltage, engineers can optimize circuits for energy efficiency, reducing unnecessary power consumption and enhancing system performance.
