What happens when a resistor is 0?

When the resistance in any circuit is equal to zero then the current passing through that circuit will be infinite.

Can a resistor have zero current?

The reason for this is that Ohm’s Law states that current through a resistor is the voltage across the resistor divided by the resistance, I=V/R. In the case of a short, the resistance is typically considered to be zero. Two resistors in parallel.

How do you determine if a resistor is shorted?

If its two terminals are connected to the same node, the resistor is short-circuited. In practical circuits, we might also say a resistor is short-circuited if a much lower value resistor is connected in parallel with it.

Does current flow through shorted resistor?

All current will bypass the resistor and travel through the short. The voltage across the 100Ω resistor is going to be zero.

What happens if a resistor is shorted in a series circuit?

A shorted resistor (resistance of 0 Ω) would theoretically draw infinite current from any finite source of voltage (I=E/0). In this case, the zero resistance of R2 decreases the circuit total resistance to zero Ω as well, increasing total current to a value of infinity.

What happens to current when a resistor is shorted?

Can current exist without voltage?

Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage.

How do resistors fail short circuits?

Generally speaking resistors fail short circuit, but a high value resistor, with a voltage across it exceeding its maximum voltage rating, can fail short by arcing over, which can drastically reduce the resistance value. I think Hero999 means generally open circuit. More often they just become higher resistance rather than becoming completely open.

What happens when more resistors are added to a parallel circuit?

Points P and Q are connected to a battery of fixed voltage. As more resistors Rare added to the parallel circuit, what happens to the total current in the circuit? 1) increases 2) remains the same 3) decreases 4) drops to zero As we add parallel resistors, the overall resistance of the circuit drops. Since V=

What happens to the current when the resistance decreases?

IR, and Vis held constant by the battery, when resistance decreases, the current must increase. Points P and Q are connected to a battery of fixed voltage. As more resistors Rare added to the parallel circuit, what happens to the total current in the circuit?

What is the difference between resistance value of AC and DC resistors?

The resistance value of the resistor in both AC and DC circuits is same irrespective of the frequency of the AC supply voltage. The change in direction of current in AC supply does not affect resistors behavior.
