Three resistances of 25 Ω, 50Ω and 100Ω are connected in parallel, drawing a total current of 15 amperes from the supply. So calculate (1) the supply voltage and (2) the current through each resistor.
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.
