A capacitor is typically placed across a resistor for the purpose of shunting either the AC component of a current (as in a transistor amplifier) or transient AC 'spikes', and is referred to as a "bypass capacitor".

Does the resistors current changes if the voltage across a fixed resistors is cut in half?
If the voltage across a resistor or resistors is halved, then the resulting current will also fall by half.
The sum of currents across the resistors equals the currents through the source in which type of circuit?
In parallel circuit the current through the resistors are different in values depending upon the values of resistors. But the sum of the currents across all the resistors will be equal to the current through the sourcgsvg bdjasuhafyuhda
What is true of a series circuit that has two resistors?
Which is true of a series circuit that has two resistors?A.The resistors are on different branches of the circuit.B.Neither resistor has current flowing through it.C.One resistor has no voltage across it.D.Both resistors have current flowing through them.
Which device contains capacitors which store enough electricity in them to cause injury and possible death to a technician and you are not to service?
High-voltage power supplies can retain the voltage in the capacitors after being switched off. However good design has resistors connected permanently across the capacitors to discharge them in 5-10 seconds after switch-off. Obviously the resistors absorb power so their value in ohms is a compromise, not usually a difficult one.
What happen to the voltage across each resistor when all of the resistors are doubled?
Nothing. But the current is halved.
Why are discharge resistors connected across large industrial capacitors?
A: Discharge or bleeder resistance are there for only one reason to bleed the charge when the power if off and unless there is a paths for those capacitors to be discharged the power stored there can be lethal to humans or detrimental to the circuit
Why load resister is conected across the circuits?
Load resistors are connected across the circuit to limit the current flowing through the load.
Resistors connected in a single path is called?
The resistors connected in single path are called series resistances or resistances in series.The current across both the resistors is same while the potential differences are different.
How are the plus and minus voltage signs determined for resistors?
Resistors have no polarity. The voltage across a resistor is determined by the direction of current flowing through that resistor (and vice versa).
When a 30.0-V emf device is placed across two resistors in series a current of 14.0 A is flowing in each of the resistors. When the same emf device is placed across the same two resistors in parallel?
There is insufficient information in the question to answer it. 30 volts generating 14 amperes means the two resistors have a total series resistance of 2.143 ohms. Since no relationship was stated, we don't know the value of the individual resistors. If the two resistors had the same resistance, the net parallel resistance would be 0.536 ohms, and a current of 56 amperes would flow.
Is capacitor a linear device?
Capacitors are linear components. A linear component is an electronic component that has a linear relationship with current or voltage in an electronic circuit. Resistors are the most common example of linear components, along with capacitors and inductors. Linear components refer to components whose output and input have a proportional relationship. For example, the relationship between the voltage across the metal resistance element and the current can be considered to be linear when the temperature remains unchanged. Metal conductors and electrolytes also have this characteristic. Electronic components have a lot of this relationship. Poor-quality components will appear "linear distortion" under certain circumstances, that is, in such a case, the input quantity and the output quantity no longer satisfy the linear relationship.

In a circuit the voltage across all resistores is the same?
It depends upon the connection of the resistors, if the resistors are connected in parallel then the voltage is same where as in case of resistors connected in series the voltage is different across different resistors.
