11/27/2023 0 Comments Amps x volts wattsI have the following solar panel with a rated output of 5.41 amps at 18.5 volts. Note: This formula is sometimes called the electrical power formula, which simply states that power equals current times voltage. The formula itself remains the same, only the abbreviated version changes. You'll often see this formula written slightly differently, with amps abbreviated as I instead of A and watts abbreviated as P instead of W. To convert amps to watts in a DC circuit, simply multiply amps by volts. How to Convert Amps to Watts for DC Circuits The current settings on the right have a wavy line with a solid line above it, indicating that those settings can measure both AC and DC current. You can see also see the AC voltage setting above it, as indicated by a "V" with the alternating current symbol (~). This multimeter is set to the DC voltage setting, as indicated by a "V" with the direct current symbol (⎓) next to it. You can see these symbols in the following picture of my multimeter. Tip: If you're ever unsure if a device uses AC or DC, look for the following symbols: a dotted line with a solid line above it (⎓) signifies DC, while a wavy line, or tilde (~) signifies AC. The phone, tablet or laptop you are reading this on uses DC power, as these devices rely on batteries to operate. The majority of the appliances in your home run on AC power.ĭC power, on the other hand, is produced by things like batteries, fuel cells, and solar panels. Amps to Watts at 5V (DC) Amps (A)Ĭonverting Amps to Watts in AC vs DC CircuitsĬonverting amps to watts is different depending on whether you're working with direct current (DC) or alternating current (AC).ĪC power is used in our modern electrical grid, as this type of electricity is easy to transmit over long distances without losses. All the AC conversion tables assume single-phase AC with a power factor of 1. Here are some tables converting amps to watts at common AC and DC voltages. Or would you rather convert watts to amps?
