What is negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
What are the three main function of the multimeter?
A typical multimeter can measure: * AC & DC voltage (volt) * AC & DC current (amp) * resistance (ohm)
What causes a meter to read negative voltage across a DC motor?
The main cause for a meter to read negative voltage across a DC motor is a loose ground wire. The ground wire can be loose or may need to be cleaned.
A circuit that adds a positive or negative dc voltage to an input sine wave is called?
clamper
How do you calculate voltage's ampere's resistances in dc automobile systems?
Ohm's Law applies where Voltage = Current x Resistance
What is negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
How to calculate the resistance to step down DC voltage?
Connect a variable resistance across DC source (fixed ends of variable resistor or Rheostat) and take decreased DC output across its one fixed terminal and other variable terminal of variable resistor. Other method is connect variable resistor in series with DC output and load, vary the resistance and take decreased DC voltage as required.
Will lower DC voltage or higher DC voltage burn out switch contacts faster if current and resistance stay the same?
if there is resistance in the contact surface , it would heat up more with higher voltage .
How do you convert DC Voltage to DC Amperage?
You don't convert DC voltage to DC amperage. You get it automaticly when you have a resistance in your circuit. Scroll down to related links and look at "Ohm's law - Wikipedia".
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
How do you decrease voltage in dc without decreasing amperage?
In order to decrease voltage without decreasing amperes you have to also decrease resistance. Ohm's Law: Voltage = current times resistance
Is 9v dc in positive or negative?
A 9V DC (direct current) supply can be either positive or negative, depending on how it is configured. Typically, in most applications, a 9V DC source is positive, meaning the positive terminal has a higher voltage relative to the negative terminal. However, if the terminals are reversed, it can be considered a negative 9V DC. The designation of positive or negative is determined by the polarity of the voltage applied.
What are the three main function of the multimeter?
A typical multimeter can measure: * AC & DC voltage (volt) * AC & DC current (amp) * resistance (ohm)
How many things can a multi meter measure?
Resistance Voltage (both AC and DC) Current (both AC and DC)
What limits the current that flows through a circuit for a particular appllied DC voltage?
The voltage applied and the resistance across it.
What are the differences in voltage drop between AC and DC systems?
In AC systems, voltage drop is affected by factors like resistance and reactance, leading to a more complex calculation. In DC systems, voltage drop is mainly influenced by resistance, resulting in a more straightforward calculation.
