What else can I help you with?
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.
What happens to the voltage values of other resistors when a short occurs in one of them?
If a short occurs in a resistor in series with other resistors, the voltage drops across the other resistors will increase. If a short occurs in a resistor in parallel with other resistors, the voltage drops across the other resistors will decrease, to zero.
How do you find resistors in parallel?
Measure the voltage appearing across each resistor. If they are identical, and equal to the supply voltage, then the resistors are in parallel.
What is the period of the voltage waveform out of a wall outlet?
60 seconds
What is a circuit that uses resistors to produce a voltage lower than the source voltage call?
A circuit that uses resistors to produce a voltage lower than the source voltage is called a voltage divider. It typically consists of two or more resistors connected in series, with the output voltage taken from the junction between them. The output voltage can be calculated using the formula ( V_{out} = V_{in} \times \frac{R_2}{R_1 + R_2} ), where ( R_1 ) and ( R_2 ) are the resistances of the two resistors. Voltage dividers are commonly used in electronic circuits for signal conditioning and level shifting.
Is the voltage constant in parallel resistors?
In parallel resistors, the voltage across each resistor is the same, but the total voltage across all resistors may vary.
Do resistors resist voltage or current?
Resistors resist the flow of current in a circuit, not the voltage.
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.
What is the physical length of a voltage waveform?
Voltage does not have a waveform. The waveform is based upon the frequency of the voltage or current. A battery (any voltage) does not waveform, however the voltage coming into your house (US) has a frequency of 60 Hz. The length of the 60 hz waveformLength (in centimeters) = (3 x (10 ** 10))/ Frequency in hz =500 000 000 cm
1 If the voltage applied across a capacitance is triangular in waveform then the waveform of the current is?
rectangular
What happens to the voltage values of other resistors when a short occurs in one of them?
If a short occurs in a resistor in series with other resistors, the voltage drops across the other resistors will increase. If a short occurs in a resistor in parallel with other resistors, the voltage drops across the other resistors will decrease, to zero.
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.
How do you find resistors in parallel?
Measure the voltage appearing across each resistor. If they are identical, and equal to the supply voltage, then the resistors are in parallel.
Two resistors are connected in parallel to a battery What must the votlage across these two resistors?
Both resistors will have the voltage of the battery.
How do you calculate average voltage of a waveform?
To calculate the average voltage of a waveform, you integrate the voltage function over one complete cycle and then divide by the period of the waveform. Mathematically, this can be expressed as ( V_{avg} = \frac{1}{T} \int_0^T V(t) , dt ), where ( T ) is the period of the waveform and ( V(t) ) is the voltage as a function of time. For periodic waveforms like sine or square waves, this average can be determined over one complete cycle. In practice, for symmetrical waveforms, the average voltage can often be simplified based on the waveform's shape.
Do resistors reduce current or voltage in an electrical circuit?
Resistors reduce the flow of current in an electrical circuit, which in turn affects the voltage across the circuit.
Why do you obtain more dc voltage than ac voltage in power supply design by using transformer?
You don't. Transformers only work with AC voltage. Their input will be an AC waveform, and their output will be an AC waveform. Other electronics are used to convert the stepped down AC waveform from the transformer to DC.
