Why are the equations for working out the current in a parrel circuit inverse?
In a parallel circuit the voltages for each component are all the same, and the current is shared, each component drawing a current depending on its conductance. In a series circuit, the current in each component is the same, and so each one gets a voltage proportional to its resistance.
What happens to metal when exposed to hot and cold?
Steel gets stronger
What happens in a fuse when the current gets too high?
It melts (fuses).
What happens if the temperature of a diode increases?
When the amount of current passing through a circuit increases, it generally increases the temperature, and consequently the resistance. Simply stated, it is harder for the current to pass through the circuit if the temperature increases. The Large Hadron Collider uses superconductors to pass current to its electromagnets. A superconductor passes current through its circuit materials with almost no resistance at all, generally by supercooling the circuit materials.
What are fuses and circuit breakers What are they for?
A fuse is a device that contain a thin strip of metal that will melt if there is too much current through it.A circuit breaker is a reusable safety switch that breaks the circuit when the current gets too high.They are used to prevent circuits from overheating.
What happens in a circuit when the resistance gets greater?
Flow of current decreases proportionately.
What happens when the water reaches the poles?
it gets cold and freezes
How is current distributed in a series circuit?
In a series circuit, all components gets the same amount of current passing through them.
What happens if the North Pole gets dark?
it gets cold
What happens in a circuit to voltage when current flows?
A: There is a relationship one needs the other both can coexists but not each alone.
What happens if you freeze stone?
it gets cold
What happens when a Lcd tv get frozen?
it gets a cold
What happens to birds when it gets cold?
They migrate to the south.
What happens to a human when it gets very cold?
they can die
What happens to a bulb if the current increases?
It gets brighter.
What effect does adding devices have on the resistance of the series circuit?
Many circuits have safety devices such as fuse. A fuse contains a substance that melts if it gets hot. if a short circuit happens, the heat causes the fuse to melt. The circuit is broken. because the current stops ,no damage is done.
Is a reusable safety switch that breaks the circuit when the current gets too high?
In the electrical trade, this device is known as a circuit breaker.
