What else can I help you with?
What happens to zener current after the breakdown voltage is reached?
After breakdown voltage is reached in a zener diode the current increases drastically.
When resistance decreases what happens to current?
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
As the voltage applied to a circuit increases the current and the also increase?
answer is actually voltage
What happens to electrical current as voltage is increased?
If everything else stays the same, power increases as EMF increases. (EMF is to volts as power is to watts.)EMF = Electromotive Force.AnswerPower is proportional to the square of the voltage. So, if you double the voltage, you'll quadruple the power... providing everything else stays the same!
Does the current ina circuit increase with increase in temperature?
Resistance increases as temperature increases. If Voltage is held constant then according to Ohm's Law Voltage = Current x Resistance then current would decrease as resistance increases.
What happens to electrical current and voltage in a parallel circuit as you add more bulbs?
Voltage remains constant; current increases.
What happens to zener current after the breakdown voltage is reached?
After breakdown voltage is reached in a zener diode the current increases drastically.
What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
What happens with electric current when applying the same voltage the resistance of the circuit is reduced?
As the resistance is reduced across the same voltage, the current increases.
What happens to current flow if circuit resistance increases and voltage remains the same?
nothing
If voltage changes in a ac circuit what happens to current?
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. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.
What is the relationship between voltage and current as shown in the graph of voltage vs current?
In the graph of voltage vs current, the relationship between voltage and current is linear. This means that as voltage increases, current also increases proportionally.
What happens to the current when the voltage becomes limited at the knee?
A: Perfect example is a zener. As input voltage increases the current at the knee increases almost linearly at the zener voltage. If the inputs varies up or down then the current will vary up or down at the preset voltage making a zener a voltage regulator because of this feature
What happens to the power in a circuit as the current increases?
P=VI If current (I) increases then P will increase proportionally. That is, assuming that voltage (V) remains constant. If voltage decreases and current increases or vice versa, proportionally then P will remain the same.
What does the current vs voltage graph reveal about the relationship between current and voltage in the given circuit?
The current vs voltage graph shows that there is a linear relationship between current and voltage in the given circuit. This means that as voltage increases, the current also increases proportionally.
What increases when current increases?
If current increases, then voltage also has to increase, assuming that resistance stay relatively the same. Power will also increase. Since power is the product of voltage and current, then the power increase would be the square of the voltage or current change.
What is the relationsip between current and voltage?
Ohm's law says Voltage = Current x Resistance. As voltage increases, currrent increases proportionally with a fixed load.
