How do you calculate voltage output?
The current flowing out of the power supply is just the voltage (5 volts) divided by total resistance, I=V/R, so: I=5R+RLED.
What is voltage VO?
The dc voltage at an output terminal with reference to a common terminal, normally ground, when no signal is applied to the input.
How do you find the VS in a circuit?
Ohms Law is used extensively in electronics formulas and calculations so it is “very important to understand and accurately remember these formulas”.
- To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
- To find the Current, ( I )
- To find the Resistance, ( R )
- To find the Power (P)
How can I calculate watts?
The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second. For example, a 60-watt light bulb uses 60 joules per second.
How do you find voltage with respect to the ground?
Calculate the voltage by multiplying the resistance and current together. The equation to measure voltage is V=R*I where R represents resistance, I is current and V is voltage, measured in volts.
How do you calculate voltage with voltage divider?
Voltage Divider Formula / Equation Equation to find the output voltage of a Divider Circuit: R2 / R1 + R2 = Ratio determines scale factor of scaled down voltage.
How do you find the electric potential in a circuit?
The equation for the electric potential due to a point charge is V=kQr V = kQ r , where k is a constant equal to 9.0×109 N⋅m2/C2.
How do you find the wattage of an appliance?
Steps
- The number of watts is equal to amps multiplied by volts. That’s it!
- For example, if the current is 3 amps (3A) and the voltage is 110V, you multiply 3 by 110, to get 330W (watts). The formula is P=3A X 110V = 330 W (with P standing for power).
- This is why watts are sometimes called volt-amps.

How do I find Thevenin voltage?
Find the Thevenin Resistance by removing all voltage sources and load resistor. Find the Thevenin Voltage by plugging in the voltages. Use the Thevenin Resistance and Voltage to find the current flowing through the load….
- Step 1 – Thevenin Resistance.
- Step 2 – Thevenin Voltage.
- Step 3 – Load Current.
