The power in watts is equal to the volts times the amps so that is 120 x 7.5.

How can you connected two heating elements each having 1000 watts to get lowest heating?
Connect the two heaters in series. The supply voltage, what ever the value, will be split in half across the two heaters. If the voltage is dropped by half across the two heaters in series, the wattage of each heater will be dropped to one quarter of the heaters wattage rating at its full voltage rating. The new wattage's will be added together for a new total wattage for the circuit. When you find the heaters working voltage use these two formulas; This one to find the resistance of the heater at its working voltage value, R = E (squared)/Watts. Then to find the watts at the reduced voltage value, W = E (squared)/R. R being the heaters resistance in ohms from the first formula.
How much does amperage drop with distance?
It is dependant on the voltage being used, size of wire, distance of the run from the distribution and load connected at the other end.
Why are domestic electric lamp circuits are connected in parallel?
If connected in series, the same current passes thru all the appliances. So, always all of them are in the same state ie all of them are running or all of them are idle. Also, if any one appliance malfunctions, it prevents current frm flowing to the other appliances and thus they also dont work. So, home appliances are always connected in parallel.Source(s):
What is tidal heating?
Tidal heating is the heating of the Earth due to being pulled on by the Moon and Sun. The Earth is constantly changing shape and heat is a by-product of that.
Should the neutral in a service panel be connected to a system ground electrode?
No, the neutral (white wire) should be connected to the center tap of the supply transformer. The electrical service that comes to your home should have 3 wires. Across the 2 black wires should be 240 VAC. That comes from a transformer that steps down from the transmission voltage that is on the high voltage lines. The "center tap" of the output of that transformer gives you 2 legs of the supply, each at 120 VAC. In years past, the center tap has often been connected to ground, but that is no longer the case. The center tap is the neutral connection, and the ground is the part that keeps you from being electrocuted.
How do you check output voltage from SMPS when it is not connect to motherboard?
If someone wants to check the voltage from SMPS even without it being connected to the motherboard that can be done by using a voltmeter. This if connected carefully can indicate the voltage.
Is flow of induced current necessary when induces emf is being produced?
There is no such thing as an 'induced current'. Voltages are induced, not currents. If a voltage is self-induced into a coil, then that voltage will oppose any change in current. If a voltage is mutually-induced into a separate coil, no current will flow unless that coil is connected to a load.
What happens to voltage in a step down?
The voltage induced into the secondary winding will be lower than the voltage applied to the primary winding. The primary winding being the winding connected to the supply, while the secondary winding is the one connected to the load.
When lightning strikes you can see the light energy being produced. What type of energy produces the thunder?
Heating of the air.
What would be the total voltage in a circuit that has two 6 volt batteries connected in series?
4 amperes. The voltage adds when batteries are connected in series. If they are the same voltage then the voltage doubles. Using Ohm's law: V = I*R with the voltage doubling and resistance being the same you get I = 2V/R and where V/R was your initial current you get I = 2*2ampers = 4 ampreres
How are voltmeter connected to circuit?
Usually a voltmeter is connected across the load whether or not it is AC (Alternating current) or DC (Direct Current). A voltmeter is never connected in series with the load as this may cause serious injury or damage. The meter will absorb the full potential .
If you connected a battery to a usb cord with some wire and connected that to another device would it charge?
depends on the voltage of the battery being used. USB voltage is 5 volts DC. If you use a car battery, which is generally 12 volts, I would think your device would not like this. But to answer your question. Yes, it will charge. But not properly if you do not use the correct voltage.
What cells are produced in spleen?
Penelstitis is connected within the veins in your brain, some of these veins lead to the spleen. And the Penelstitis produces the blood as the blood vessels are being mulitiply produced.

What happens to voltage in a step-down transformer?
The voltage induced into the secondary winding will be lower than the voltage applied to the primary winding. The primary winding being the winding connected to the supply, while the secondary winding is the one connected to the load.
What are voltage dividers?
Voltage dividers are used in a linear circuit to separate the input voltage into a small portion known as the output voltage. It is commonly used to get a low voltage signal equal to the voltage being measured.
