Solution

The correct option is A composition type resistor and film type resistor
Carbon resistors are of two types composition type resistor and film type resistor.

There are a number of different types of fixed resistor:

Carbon composition: These types were once very common, but are now seldom used.

Carbon film: This resistor type is formed by "cracking" a hydrocarbon onto a ceramic former.

A manufacturer of electronic circuits has a stock of 200 resistors, 120 transistors and 150 capacitors and is required to produce two types of circuits A and B. Type A requires 20 resitors, 10 transistors and 10 capacitors. Type B requires 10 resistors, 20 transistors and 30 capacitors. If the profit on type A circuit is Rs 50 and that on type B circuit is Rs 60, formulate this problem as a LPP, so that the manufacturer can maximise his profit.

Q. Assertion :A liquid rheostat is a type of variable resistor,which may be used as a dummy load or as a starting resistor for large slip ring motors. Reason: The salt water rheostat operates at unity power factor and presents a resistance with negligible series inductance compared to a wire wound equivalent.

Q. A carbon film resistor has colour code Green Black Violet Gold. The value of the resistor is:
