Current is the flow of electric charge, typically measured in amperes (A). Voltage is the potential difference between two points, typically measured in volts (V).
Current can be calculated by dividing the voltage by the resistance, using Ohm's Law: I = V/R. It can also be calculated by dividing the charge by the time, using the equation I = Q/t.
Equivalent resistance is the total resistance in a circuit, when multiple resistors are connected in series or parallel. It can be calculated using Ohm's Law or by combining the resistances using specific formulas for series and parallel circuits.
Voltage can be measured using a voltmeter, which is connected in parallel to the circuit. The voltmeter measures the potential difference between two points in a circuit.
Yes, current and voltage can be either positive or negative. A negative value indicates the direction of the flow of current or the potential difference between two points in the opposite direction.
