Two resistors are connected in series. One resistor has a resistance of 1000 ohms, and the other resistor value is unknown. the circuit is connected to a 30V power supply and there is a current of 25mA flowing in the circuit. if a 1500 ohms resistor is connected in parallel with the unknown resistor, how much current will flow in the 1500 ohms 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.
