How do you calculate voltage's ampere's resistances in dc automobile systems?
Ohm's Law applies where Voltage = Current x Resistance
How you can change a constant DC voltage to a variable DC voltage?
By installing the varialble resistor in the circuit,the constant dc voltage would change .
What value of voltage measure by DMM Vrms or Dc voltage?
Many can measure both - Vrms (AC) or DC voltage.
What device used to increase or decrease DC voltage?
A DC-to-DC converter is the general term for a device that changes DC voltage at one level to another.
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
How do you calculate voltage's ampere's resistances in dc automobile systems?
Ohm's Law applies where Voltage = Current x Resistance
How do you calculate DC power if voltage and currents are given?
P = E * I Power (watts) equals voltage (E) times current (I)
How do you calculate the dc circuit breaker rating for a given kw?
the given kw Divide by the your voltage
How can calculate resistance for negative dc voltage?
Resistance calculations are the same no matter what the polarity of applied voltage. R=E/I Resistance (in ohms) = Voltage (in volts) divided by Current (in amperes)
How you can change a constant DC voltage to a variable DC voltage?
By installing the varialble resistor in the circuit,the constant dc voltage would change .
How do you convert 23 voltage DC to 230 Voltage AC?
How do you convert 23 voltage DC to 230 Voltage AC?
What is meant by DC-DC luo converter?
luo converter is a new technique adopted for dc to dc voltage lifting(dc voltage boosting)...
How is DC voltage represented on multimeters?
DC
What is excitation of a DC motor?
DC Voltage
What is commutation in DC machines?
It is the process of conversion of generated ac voltage into the armature of a dc generator to dc voltage at the terminal of the dc generator by use of pair of brushes and commutator. OR It is the process of conversion of given dc voltage at the terminal of the dc motor to ac voltage in the armature windings in a dc motor by use of pair of brushes and commutator.
What value of voltage measure by DMM Vrms or Dc voltage?
Many can measure both - Vrms (AC) or DC voltage.
What voltage is DC?
A voltage DC(direct current voltage) is a uni-direction steady voltage. It is the opposite of an analog/alternative voltage which varies in polarity and direction with time.
