Electricity is conventionally described as flowing from positive to negative due to historical conventions established by Benjamin Franklin, who defined the direction of electric current before the discovery of electrons. In reality, the flow of electric current in most conductors is due to the movement of negatively charged electrons, which move from the negative terminal to the positive terminal. However, the conventional flow direction remains useful for circuit analysis and design, even though it does not reflect the actual movement of charge carriers.

To wire two baseboard heaters to one thermostat, first ensure the power is turned off at the circuit breaker. Connect the two heaters in parallel by joining their corresponding wires: connect the hot wires (usually black) from each heater to the thermostat's hot terminal, and connect the neutral wires (usually white) together. Finally, connect the ground wires (bare or green) to the grounding terminal. After securing all connections and properly mounting the thermostat, restore power and test the system. Always follow local electrical codes and consider consulting a licensed electrician if you're unsure.

To find the amps a 1200-watt microwave uses on a 120-volt plug, you can use the formula: Amps = Watts / Volts. Therefore, 1200 watts divided by 120 volts equals 10 amps. So, a 1200-watt microwave uses approximately 10 amps when plugged into a standard 120-volt outlet.
