How much power is 1.5 amps?

I'm curious, can you explain to me how much power is represented by 1.5 amps? I understand that amps are a measure of electric current, but how does that translate into the amount of power being used? Is there a formula or equation that can help me understand this better? Additionally, are there any factors that can affect the power output at a given amperage? I'd appreciate any insight you can provide on this topic.
