Homework Statement
Why has current been defined to be a scalar?
Homework Equations
The Attempt at a Solution
No idea whatsoever!
Current is the rate of flow of electric charge in a circuit, measured in amperes (A).
Current is defined as a scalar because it only has magnitude and does not have a specific direction. It is simply a measure of the amount of charge flowing in a circuit.
Voltage is the driving force that pushes electric charges through a circuit, while resistance is the measure of the opposition to the flow of current. Current, on the other hand, is the actual flow of charge in the circuit. They are all related through Ohm's Law: V=IR.
Yes, current can be negative. This indicates that the flow of charge is in the opposite direction, or that the charge carriers are negatively charged particles, such as electrons.
Current is measured using an ammeter, which is connected in series with the circuit. The ammeter measures the amount of charge passing through a specific point in the circuit per unit time and displays it in amperes (A).
