Find the power for each resistor, current, and total power of circuit
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.
Find the power for each resistor, current, and total power of circuit
As we know that the power absorbed or dissipated by a resistor P= I2R =VI
Here I is the current through respective resistor and R is the value of resistance in ohms and V is voltage across the R resistor and hence the unit of P will be Watt.
