At 115 volts of current, 115 watts is equal to one amp, but the number of watts to equal an amp varies based on the current. If using a 12-volt battery to power the circuit, 12 watts is equal to one amp. More »

Power in watts equals amperes times voltage. So, in a direct current, 1 amp at 110 volts equals 110 watts, whereas 1 amp at 220 volts equals 220 watts. More »

Watts cannot be calculated using the number of volts alone. Amperage is required, too. More »

While there is no specific limit to the number of electrical outlets that can be installed on a single 15 amp breaker, the total load cannot exceed 1,800 watts. This number is calculated by multiplying the standard volta... More »

It is possible to connect a 6-ohm speaker to an 8-ohm amp. While the internal impedance of the speaker is 6-ohms, the output impedance of an amplifier is essentially zero. This is due to the active control circuitry in m... More »

Bridging an amp requires red and black speaker wire that can be connected to the back of the amp. Before trying to bridge an amp, check the documentation that came with the device to ensure bridging is possible with that... More »
