A resistor held in running water carries electric current. Treat the resistor as the system. Does heat flow into the resistor?

A resistor held in running water carries electric current. Treat the resistor as the system. Is there a flow of heat into the water?

A resistor held in running water carries electric current. Treat the resistor as the system. Assuming the state if resistance to remain unchanged, apply the first law of thermodynamics to this process.

Answer the following questions : Statement 1: Electric current (flow of electrons) creates heat in a resistor. Statement 2: Heat in the resistor is created according to the law of energy conservation. Explain statement 1 with the help of statement 2.

Statement I : Electric current creates heat in the resistor. Statement II : Heat in the resistor is created according to the rule of conservation of energy. Explain Statement I with the help of Statement II.

Choose correct alternative. When resistors are connected in parallel combination A. Potential difference across each resistor is same B. different current passes through unequal resistors C. equivalent resistance is equal to sum of the reciprocals of the resistors in the combination D. Both A & B

Questions based on paragraph While performing an experiment on electric current, a student was given different electrical components such as conducting wires, ammeter, voltmeter, 9V_ battery, plug key, three identical resistors ( 6 Omega, 6 Omega and 6 Omega ). Calculate the electric current, if all the resistors are connected in series.

Material used as resistor in an electric heater

The current through the 6Omega resistor shown in figure is

Answer the following When resistors are connected in series, they are connected one after another. If any one of them does not function, the circuit breaks and there is no flow of electricity. If two give less individually. If three bulbs are connected in series, their light output will decrease further. Think about it: What is the reason behind this?
