I (A) = P (W) V (V) So, the current I in amps is equal to the power P in watts divided by the voltage V in volts. For example, let’s calculate the amperage of a 100-watt light bulb at 120 volts. amps = 100 W 120 V. amps = 0.83 A. A 100-watt light bulb at 120 volts will draw 0.83 amps of current.
In short, you can measure the DC voltage with a multimeter by following these steps. First, switch the dial to DC Voltage. Next, put the black probe inside the COM jack and the red probes inside the V Ω jack. Next, remove the red probe first and then the black probe. Next, connect the test probes to the circuit.
To reduce voltage in half, we simply form a voltage divider circuit between 2 resistors of equal value (for example, 2 10KΩ) resistors. To divide voltage in half, all you must do is place any 2 resistors of equal value in series and then place a jumper wire in between the resistors. At this point where the jumper wire is placed, the voltage
To convert 440V AC to 24V DC, you can use a step-down transformer to reduce the voltage to a lower level, and then rectify and filter the output to obtain 24V DC. What is the formula for DC voltage? The formula for DC voltage is VDC = Vpeak * 0.9 (for a full-wave rectifier).
V (V) = P (W) I (A) × PF. For an AC circuit, the voltage V in volts is equal to the real power P in watts divided by the product of the current I in amps and the power factor. For example, let’s convert 1,300 watts to voltage for an AC electrical circuit with 12 amps of current and a power factor of 0.9. V(V) = 1,300 W ÷ (12 A × 0.9)

For three-phase AC, the formula is, I= P/√3*V*P.F. If P is 2500 watts, the voltage is 220 V, and the power factor is 0.8. Then, the amperage of single-phase AC will be, I= 2500/√3*220*0.8= 8.200997 amps.
