You have a 30 V source and two resistors: R1 = 10 Ω and R2 = 25 Ω. Find the current in a circuit with the resistors connected in parallel. What is the current through each resistor if they are connected to the power supply separately? CHOICES: 4.2 A,1.2 A, 3 A 4.2 A, 3 A, 1.2 A 1.2 A, 4.2 A, 3A 1.2 A, 3 A, 4.2 A
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.
