Calculatorand allFormulas Resistance(ohms),current(amps), andvoltage(volts) Ohm's Law is the linear proportionality between current and voltage that occurs for most conductors of electricity. A graph of voltage against current is a straight line. The gradient is the resistance. ...
If only one is known, you need resistance or the other value (current or voltage) to compute power using other laws like Ohm's Law (V = IR). What does a negative power value signify?A negative power value usually indicates that a component or system produces or exports power rather ...
