Quick Answer: How Many Ohms Is 60 Watts?

How do you calculate resistance to Watts?

Determine resistor wattage.

If you want to know wattage of a resistor, you will need to know the voltage (V) and the current (known as I).

This is called Ohm’s law.

The multiplication formula is voltage multiplied by current, expressed as W=V X I.

How many ohms is 100 watts?

144 ohmsFor example, a 100 watt light bulb operating on 120 volts AC will have 144 ohms of resistance and will draw 0.833 Amps.

Which has more resistance 100w or 60w?

For a give voltage V, P is inversely proportional to R. So the 60 W bulb will have more resistance than the 100 W bulb.

Which one has a higher electrical resistance a 100 watt bulb or a 60 watt bulb?

A 60-watt bulb has a higher electrical resistance than a 100-watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high.

What is the internal resistance of a 12v car battery?

0.02 ohmsThe internal resistance of a 12 volt car battery is 0.02 ohms. What is the maximum power it can deliver? – Quora. The internal resistance of a 12 volt car battery is 0.02 ohms.

How many ohms is a watt?

Volts to ohms calculation with watts The resistance R is equal to square of 5 volts divided by 2 watts, which is equal to 12.5 ohms.

How many ohms does a 9 volt battery have?

You can model your battery as an “ideal” 9 V battery with a series resistance. From you measurement you can calculate that the battery’s internal resistance. R=VI=90.2=45 Ω.

What is the resistance of 60 watt bulb?

In fact, the 120-Watt bulb would have a current of 1 Amp and a resistance of 120 Ω; the 60-Watt bulb would have a current of 0.5 Amp and a resistance of 240 Ω.

What is internal resistance of battery?

Internal resistance refers to the opposition to the flow of current offered by the cells and batteries themselves resulting in the generation of heat. Internal resistance is measured in Ohms. … Example: 1 The potential difference across the cell when no current flows through the circuit is 3 V.

Which has a larger resistance A 60 W?

If the voltage of two bulbs is assumed to be the same, the resistance of the bulbs equals to V/100 and V/60 respectively. Thus, it is proved that the 60W bulb has higher resistance than the 100W bulb.

How many watts is 220 volts?

How many watts/volt in 1 watts/220 volts? The answer is 0.0045454545454545. Note that rounding errors may occur, so always check the results.

How many watts are in an amp hour?

The key is to use the watts you know to calculate the amps at the battery voltage . For example, say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours. Amp-hours (at 12 volts) = watt-hours / 12 volts = 1470 / 12 = 122.5 amp-hours.

How many ohms does a AA battery have?

Batteries will always have some resistance. Though the internal resistance may be or appear low, around 0.1Ω for an AA alkaline battery, and about 1Ω to 2Ω for a 9-volt alkaline battery, it can cause a noticeable drop in output voltage if a low-resistance load is attached to it.
