What is the net resistance of the circuit connected to the battery in the figure?
To find the net resistance of the circuit connected to the battery in the figure, you need to calculate the total resistance by adding up the individual resistances in the circuit.
How do you figure out resistance?
Turn off circuit. Then you can use a meter set for resistance, clip onto both ends of the resistor, meter will display the resistance in ohms.If you know the voltage and amperage you can use Ohm's Law: E=IRR=E/IR is resistance, E is voltage, and I is current (amperage)
How do you figure power lost as heat in electricity?
To calculate power lost as heat in electricity, you can use the formula P = I^2 * R, where P is the power lost in watts, I is the current in amps, and R is the resistance in ohms. This equation is based on Ohm's Law (P = V^2 / R) and Joule's Law (P = I^2 * R), which relate power, voltage, current, and resistance in an electrical circuit. By knowing the current and resistance in a circuit, you can determine the power lost as heat.
What is the resistance of two light bulbs in a series if one is 30watts and the other is 40watts with a 120volt battery?
This problem involves two steps. First we need to figure out the amount of current in each light bulb. Then we use that value to find our two different resistances using Ohm's Law, and combine them to find our total resistance of the two bulbs. For the first step, we need to know that the 30 and 40 watts they give us describe the light bulb's power, which is the rate at which they transform electricity into light and heat. There is an equation in physics which states that the power of a light bulb or other resistor (any object that takes up electricity in a circuit), is equal to its current, measured in amps, multiplied by the volts supplied by the battery. In equation form, P=IV, where P=power, I=current, and V=volts. We need I to find our resistance for the bulbs later. The power of the first bulb is 30 watts, and the volts equals 120 V, so 30=I(120). I works out to be .25 amps for the first bulb. The second bulb has a power of 40 watts, but receives the same amount of volts as the first bulb because they are in the same circuit. So for the second bulb, 40=I(120), and I works out to be .333 amps. Now because we have the resistances, we can use Ohm's Law for both bulbs. Ohm's Law states that the current equals the the voltage divided by the resistance, or I=(V/R). To make this easier, I'll change the equation a bit. We can multiply both sides by R to get IR=V, and then divide by I to get the new equation, R=V/I. This makes it easier for us to find our resistance directly with our values. Then we simply plug in our I values which we found and the voltage of the battery to figure out the resistances. The first bulb's equation is R=120/.25, and the second bulb's equation is R=120/.333. Solving for the R's, the first bulb has a resistance of 360 Ohms, while the second bulb has a resistance of 480 Ohms. If you just wanted the individual resistances, then those are your answers. But because you told me they were in series, it seems to me that you want their total resistance. We can find the total resistance for resistors in series by simply adding the resistances up. In this case, our total resistance would be 360 Ohms plus 480 Ohms, or 840 Ohms. Take a look at the links below for more information. The first one explains the relationships between current, voltage, and resistance, and the second link discussed finding resistance in series and in parallel as well.
What are the formulas of series connection?
The following rules apply to a parallel circuit:The potential drops of each branch equals the potential rise of the source.The total current is equal to the sum of the currents in the branches.The inverse of the total resistance of the circuit (also called effective resistance) is equal to the sum of the inverses of the individual resistances.One important thing to notice from this last equation is that the more branches you add to a parallel circuit (the more things you plug in) the lower the total resistance becomes. Remember that as the total resistance decreases, the total current increases. So, the more things you plug in, the more current has to flow through the wiring in the wall. That's why plugging too many things in to one electrical outlet can create a real fire hazard.

How to figure amps in an electrical circuit?
To figure out the amps in an electrical circuit, you can use Ohm's Law, which states that Amps Volts / Resistance. Measure the voltage across the circuit and the resistance of the components in the circuit, then divide the voltage by the resistance to calculate the amperage.
How to figure out ampreage in a circuit?
For a d.c. circuit, you divide its supply voltage by the resistance of its load. For an a.c. circuit, you divide its supply voltage by the impedance of its load.
How do you compelete the circuitry mission 6 on the 39 clues?
Look at where the battery is placed and you'll see one square with a piece that has three ends right to the left of the battery. This is the start of the circuit and this piece has to be placed so one end is connected to the battery and the other ends are point up and down. From there, the rest of the circuit should be pretty easy to figure out. Good luck! :)
How do you figure out how much current is in an electrical wire?
If you know the voltage and resistance, then current = voltage divided by resistance. Otherwise, you can attach an ammeter into the circuit (in series).
What is external resistance?
External voltage is the ration when there is an increase in current and voltage. If you apply voltage to the outside of a circuit and need to figure out the amount of current flow, that would be the external resistance.
How do you figure out what is causing a drain on the battery battery and alternator are functioning properly?
Could be a bad voltage regulator or Connect a test light in series with - battery cable Remove fuses one at a time until light goes out - that will tell which circuit has current flow, then check that circuit for defect
To which biblical figure is Grendel connected?
Grendel is connected to the biblical figure Cain.
How is Ohm's Law used?
Ohm's Law relates Voltage, Current, and Resistance. The equation is Voltage = Current times Resistance. Knowing any two, you can figure out the third, and that is one of the principles of basic circuit analysis.
