I am a component that conducts electricity, without me, circuits can't function with efficacy. From copper to aluminum, I'm made, my size and length can be customized and swayed . What am I ?

I am a device that stores electric charge , with two plates that are close but never at large. When voltage is applied, I store energy so neat , and my capacity to hold it makes me quite a treat. What am I ?

I am a device that measures

resistance, with four arms that

form a balanced instance. Voltage

applied, and current flows

through,  but if there’s a

difference, it’ll give a clue. What am I ?

I am a component that slows down the flow, of electric current that's ready to go. My job is to limit, to reduce the speed, and without me, circuits would surely exceed. What am I ?

Which component is used to control the flow of current in a circuit?

I am a device that measures electric flow, with a delicate needle that's ready to show. I'm used in labs, to test circuits and more, and my readings can help troubleshoot what's in store.What am I ?

From digital to analog, I come in style, with a display that makes you smile. My internal resistance is low , for accurate readings, I never bow. I can measure current in a circuit, from a power supply or a battery, that's lit .

What am I?

I am a device that measures volts, With a display that never faults , From AC to DC, I can measure all, With accuracy that stands tall. What am I ?

I am a component that's quite bright,

in circuits, I emit colored light. With a forward voltage and low current, my brightness is quite efficient. What am I?

I am a tool with many functions to display. A true Swiss army knife for the electrician's way. With a digital screen and a probe to test , I can measure voltage, current, and all the rest. What am I ?

I am a switch that's double-pole, With four terminals I'm on a roll. When flipped on, I'll connect two things, And turn off power like a king. What am I?

What happens to the resistance of a wire when its length is doubled?

 I am a component with a one-way flow, current through me can only go . With a PN junction, I'm made , my function is quite an aid . From rectification to protection , I serve with utmost dedication . My forward voltage is quite low , for a drop of current, I'm the pro. What am I ?

I am a machine that turns and spins, converts electrical energy into motion, wins. With brushes and commutator, I operate , my power source is direct, so don't hesitate. What am I ?

I am a device that changes voltage and current , and can make electrical power more efficient . I work through electromagnetic induction , and can step up or down voltage with precision. What am I ?

With my AND, OR and NOT,I can make calculations a lot . XOR and NAND, they're in my range , With them, I can perform logic strange. What am I ?

I have a screen but I'm not a TV,I display waves but I'm not a beach,I have a cathode ray but I'm not a nuclear reactor. What am I ?

I am a coil of wire with a magnetic field,

And when current flows through me, my power is revealed.

I store energy in my magnetic field so true,

And my resistance to change is what makes me useful too.

What am I?

I am a component that's sensitive to heat,

My resistance changes, with a temperature beat.

I'm used in thermostats, to keep things in range,

And my readings can help to prevent overheating or change.
