What can you do to conserve energy?
You can perform reversible Work: stretching a spring - you can look at some old watches and see the mechanism. you can put electric current into a Capacitor.
How much a 5-pound weight would stretch the spring?
It depends on spring energy or spring strength
What is it called when the coils of a spring are spread out?
The spring has been stretched. When the coils are squeezed together then the spring has been compressed.
Why is a spring needed in the lock of a door?
Without a spring, the lock would never unlock. Therefore, a lock of a door required a spring.
Suggest suitable Experiments to find spring constant of a helical spring?
Connect a mass to the bottom of the spring. (depending on the spring size, the mass will vary, the larger the spring the greater the mass u can use) Suppose you use a 100 g mass on a spring, measure the amount by which it stretches and record the data. Use hooke law to figure out the constant of the spring. K = m.g/x m = mass, g =gravity, x = stretch
What happens when a direct current is passed through a helical spring?
in an adjacent coils ,the current flows in same direction so there is force of attraction shortening the coils.
A metallic weight is suspended from a metal spring. If now a current is passed through the spring which will happen?
The current passing through the spring will generate heat due to the electrical resistance of the metal. This heat could potentially cause the spring to expand or change its mechanical properties, leading to a change in the weight's position or the spring's behavior. Additionally, the magnetic field generated by the current may interact with the weight if it is magnetic, causing it to move.
Why does a metal spring contract when an electric current is passed through it?
When an electric current passes through a metal spring, it generates heat due to the resistance of the metal. This heat causes the metal atoms to vibrate more and the spring to expand. Once the current stops, the spring cools down and contracts back to its original size.
What happens when electric current passes through a spring?
When electric current passes through a spring, the spring can become magnetized. The magnetic field generated by the current induces a magnetic field in the spring, causing it to act like a magnet. This magnetic property can be harnessed in various applications, such as in electromagnets or speakers.
What happens when electric current is passed through acidified water?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What is Primary Current?
Primary current is a flow to be measured that cannot be safely passed through the measuring device. A current transformer is used to provide a lower level, secondary current that can be passed safely through the measuring device. Primary current is measured as a secondary current, multiplied by the turns ratio in the current transformer.

Why D.C. current is not passed from our body?
Lightning is a DC current and it will pass through your body with devastating effect. Defibrillators use a DC current to restart/reset your heart if it has stopped or gone into fibrillation. So DC current is passed through your body.
Do the conductors charge when a current is passed through them?
Yes, conductors do charge when a current is passed through them because the movement of charge carriers (electrons) within the conductor creates an electric field. This field causes charged particles within the conductor to redistribute, leading to a net charge buildup.
Does nichrome wire get red hot when current is passed through it?
Yes, nichrome wire gets red hot when current is passed through it due to its high resistance, which causes it to generate heat. This property is used in applications such as heating elements in appliances.
