What is the relationship between power, voltage, and current, and how can it be expressed mathematically using the formula power equals voltage multiplied by current?
The relationship between power, voltage, and current can be expressed mathematically using the formula: Power Voltage x Current. This formula shows that power is directly proportional to both voltage and current. In other words, an increase in either voltage or current will result in an increase in power.
How can you solve for resistance when given power?
You can solve for resistance using the formula ( R = \frac{V^2}{P} ), where R is the resistance, V is the voltage, and P is the power. By rearranging the formula, you can solve for resistance by dividing the square of the voltage by the power.
Current times resistance equals what?
The voltage across a resistor multiplied by the current flowing through it equals the power dissipated by the resistor, according to Ohm's Law (P = V * I). So, the relationship between current and resistance is not directly related in that way.
What does the power vs voltage graph reveal about the relationship between power consumption and voltage in a circuit?
The power vs voltage graph shows that power consumption in a circuit is directly proportional to voltage. This means that as voltage increases, power consumption also increases.
Is power proportional to voltage squared?
Yes, power is directly proportional to current. Power is equal to amps times volts, and as current goes up (with voltage remaining constant), power will go up. Double current, and you'll double power. Cut current in half, and you'll cut power in half. (Voltage stays the same in all this).
Does voltage divided by watts equal the current?
Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
How do you calculate DC power if voltage and currents are given?
P = E * I Power (watts) equals voltage (E) times current (I)
What is the role of voltage in an electrical circuit?
Voltage is related to energy by charge. Power equals voltage times current (amperes), and energy equals voltage times charge (coulombs).An ampere is 1 coulomb of charge moving per second.A watt (power) is 1 joule of work done (or energy transferred) per second.
How do you calculate electrical power?
Voltage x current. In a resistor for example it is the voltage drop across it that is relevant, it may be part of a circuit.
How do you determine the power supplied to a motor with 1.0mA of current at 3.0V potential difference?
current times voltage equals watts or power
How do you calculate power loss from a resistor?
The power dissipated across a resistor, or any device for that matter, is watts, or voltage times current. If you don't know one of voltage or current, you can calculate it from Ohm's law: voltage equals resistance times current. So; if you know voltage and current, power is voltage times current; if you know voltage and resistance, watts is voltage squared divided by resistance; and if you know current and resistance, watts is current squared times resistance.
Find an expression for power that involves only current and voltage?
That is the basic one. P=I*E. Power in watts (P) equals current flow in amps (I) times the potential voltage (E) in volts.
What is the formula for power delivered by a voltage source?
Power is voltage times current.
What is the decibel voltage for these number P1 equals 100 p2 equals 50?
Decibels describes changes in power, not voltage. If the question meant to say value instead of voltage, then a power change from 100 to 50 is -3 decibels, or -3dB.Decibels is 3 log2 (POWER OUT/POWER IN).
What is the power dissipated by a resistor that has 5 amps flowing through it with 120 volts applied?
The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
What is equal to voltage times current?
Power, in 'watts'.
