Which of the following are true? i. Ohm’s law utilizes resistance, current, and voltage. ii. Ohm’s law was named after the mathematician and physicist George Sian Ohm. iii. Ohm’s law is the most powerful mathematical tool used in the study of electricity. iv. Ohm’s law is useful in analyzing circuits. What is the appropriate question for the following: i. to decrease the resistance of electrolysis ii. to increase the resistance of alloys iii. to increase the resistance of pure metals
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.
