The formula you are looking for is Watts = Amps x Volts.
On 120 volts seven could be used, on 240 v fourteen of them.
Volts are used to measure the electrical potential difference or voltage in a circuit. To use volts, you would typically measure the voltage across a component in a circuit using a multimeter or voltmeter. This helps in determining if the component is receiving the correct amount of voltage for proper operation.
The current (ampere) changes from a high value at switch on to a run current of of approx 0.5 amperes. The fuse blows at switch on if too many lamps are connected. It also depends on the cable used to wire up the lamps and the length of the cable.
In the United States toasters run on 120 volts.
Circuit breakers are typically designed for lower voltages, such as up to 1000 volts. For extremely high voltages like one million volts, special high-voltage circuit breakers or other protection devices would be used in power systems. These specialized devices are designed to handle the unique challenges posed by very high voltage levels.
Philips lamps in the USA have a minimum of 12 volts suggested. This can vary according to the lamps and bulbs used and also for the location of the lamp and its usage.
Each light bulb will receive the full 9 volts from the battery in a series circuit, so each bulb will be operating on 9 volts.
If you meant 60w (or watts) then it is used primarily in small table lamps and closets. If you meant 60 v (or volts) then you could use it in series with another 60v bulb on a standard household 120v circuit.
On 120 volts seven could be used, on 240 v fourteen of them.

Assuming that your voltage is 120 volts the maximum wattage on that circuit is W = A x V = 15 x 120 = 1800 watts. Code only allows circuits to be loaded up to 80% capacity. 1800 x .8 = 1440. 1440/25 = 57 lamps. Assuming that your voltage is 240 volts the maximum wattage on that circuit is W = A x V = 15 x 240 = 3600 watts. If the question is from a 240 volt country you will have to find out what the local electrical regulations are for circuit loading.
A voltmeter is used to measure voltage, which is typically expressed in units of volts. This device is commonly employed in electronic circuit testing and troubleshooting to determine the electrical potential difference between two points in a circuit.
heat lamps are used for many purposes ,but I think you should put them on your head to warm your brain.
It depends what the other components of the circuit are. If you use a 24 volt battery set up, and the load is designed for 12 volts, you may burn out the load. For example, 12 volt automotive lamps will burn brighter but will fail sooner if powered by 24 V instead of 12 V.
The purpose of a voltmeter is to measure the number of volts contained in a wire. If the number of volts is too high then the wire can't hold in all of the volts and you get shocked. ================ Beautiful. A voltmeter is used to measure the potential difference between two points, usually but not always in an electronic circuit comprised of many components.
The circuit designer typically picks a family of devices to implement the functionality of the circuit. The devices will fall into a range of voltages. Many integrated circuits operate at 5VDC, so it is an obvious choice for many applications.
