Concept explainers

KVL and KCL

KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.

Sign Convention

Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.

Which of the following statements regarding circuits are true? To find resistance in a parallel circuit, you must sum the individual resitances The direction of conventional current is the direction of positive charge flow. In a circuit, electrons flow from high potential energy (at the negative terminal) to low potential energy (at the positive terminal). When electricity is passed through a lightbulb, the electrons are 'used up' by the bulb. All voltages in a loop sum to 12V The current that flows into a resistor is the same as the current that flows out. To 'short circuit' something means there is an alternate path of less resistance for the current to flow. Switching on a light happens immediately because electrons move from the power source to the bulb incredibly quickly. A 'kilowatt-hour' is a unit of power, not energy.
