If I0 = V/R, then Inew = (2*V)/(.5*R) = (2 / .5) * (V/R) = 4 *V/R = 4 * I0

Voltage across resistor is doubled the current is?

Ohm's law states that the voltage across a resistor is the product of the current times the Resistance or V=I x R (I times R). V is Voltage, R is Resistance, and I is Current or Amperage. So if the Voltage is doubled and Resistance stays the same, the Current will be doubled.


What is the effect on current in a wire if both the voltage across it and its resistance are doubled?

it will cause a Short Circuit


What happen to the voltage across each resistor when all of the resistors are doubled?

Nothing. But the current is halved.


What is the effect on the current in a wire if both the voltage across it and it's resistance are doubled?

By Ohm's Law, current is voltage divided by resistance, so if you double both the voltage and the resistance, the current would remain the same.


What is leakage resistance?

leakage resistance of a resister is type of fault which occurs at a specific voltage across the resister which are undertesting.


What should the current be through a bleeder resister in a voltage divider circuit?

The current should be high enough to maintain the voltage at each division. Generally, the current should be ten times the load current or the voltage will be across the voltage divider. If possible use regulators or zeners or regular diodes. I'm not saying dividers are bad but there are less current sensitive solutions.


Potential difference across resistor is doubled?

If the potential difference across a resistor is doubled, the current flowing through the resistor will also double, assuming its resistance remains constant. This relationship is described by Ohm's Law, where current is directly proportional to voltage when resistance is held constant.


What happen is the potential difference across is double?

If the potential difference across a circuit is doubled, the current flowing through the circuit will also double, assuming the resistance remains constant. This is because Ohm's Law states that current is directly proportional to voltage when resistance is held constant.


What is a 1.5 omega resister?

The capital Greek letter Ω (omega) is the symbol for Ohms - the unit of resistance. A 1.5Ω resister is a resistor with quite a low resistance. If a voltage of 1.5 Volts is applied across it, a current of 1 Amp[ere]s will flow through it.


Does a resister use current?

It may be better to say that a resistor allows current flow through itself rather than to say that a resistor is a device that will "use" current. It does "resist" current flow, and thus limits it to some degree depending on its resistance. (More resistance means more limiting of current flow.) The resistor "drops voltage" as well limits current. A resistor "feels voltage" from some source, and the voltage it "feels" is said to be the "voltage drop" of the resistor. The voltage drop is the voltage that could be measured across that resistor with a meter.


How does the voltage across a capacitor change over time when a current is flowing through it?

When a current flows through a capacitor, the voltage across it increases or decreases depending on the rate of change of the current. If the current is constant, the voltage remains steady. If the current changes rapidly, the voltage across the capacitor changes quickly as well.


Why load resister is conected across the circuits?

Load resistors are connected across the circuit to limit the current flowing through the load.
