Practice Karnataka SSLC (Class 10) Electricity in the app →The SI unit of electric current is theIn a circuit, an ammeter and a voltmeter are correctly connected respectivelyOne volt of potential difference is defined asThe SI unit of electrical resistance is theOhm's law states that at constant temperature the current through a conductor isThe resistance of a metallic wire isWhich material is used for the heating element of appliances like electric irons because of its high resistiviWhen three resistors are connected in series, the equivalent resistance isFor resistors in parallel, the reciprocal of the equivalent resistance equalsTwo resistors, each of resistance $R$, are connected in parallel. Their equivalent resistance isThe electric power dissipated in a resistor can be written asJoule's law of heating states that the heat produced in a resistor isA potential difference of 12 V is applied across a $4\ \Omega$ resistor. The current through it isThe commercial unit of electrical energy, '1 unit', isDomestic electrical appliances are connected in parallel rather than in series mainly becauseIf the resistance of a component is kept constant and the voltage across it is doubled, the current through it
