Describe the energy transformations that take place when a battery is connected to a light bulb in a series circuit?
Chemical/ potential energy to electrical energy to light energy and heat energy
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
a circuit is a pathway in which electricity travels a very basic circuit is a battery connected to a light connected back to the battery circuits always travel back to where they started or the circuit is not complete and does not accomplish the desired task all electronics have either a very complex circuit, a simple circuit, or a series of circuits
What will happen when a wire is connected to the positive end of a fresh battery if there is nothing else in the circuit?
A capacitor that is suddenly connected to a battery will charge to the battery voltage. The time to do this is dependent on the current capacity of the battery and wiring, and the capacitance of the capacitor. This represents an instantaneous short circuit, which lasts for a (usually) very short time - but damage could be done if there was no resistance. A charged capacitor that is suddenly disconnected from a battery will hold that…
That completely depends on how much current is used by the circuit or device that's connected to the battery. For example, if there is no circuit or device connected to the battery, and no current is used, then the battery lasts for quite a long time. But if you lay a screwdriver across the battery terminals and create great balls of fire, then the charge on the battery may only last for 1/2 second.
Your battery-powered flashlight is a good example of a DC series circuit. Battery power is DC. The battery is connected to a wire or piece of metal that's connected to a switch that is connected to an incandescent light bulb (resistor/thermistor) which is then connected to another piece of metal or wire which is connected to usually a spring in the end of the flashlight which creates a ground to the negative terminal of the…
If you know the resistance of the circuit connected to the battery, or if you can measure it with your ohmmeter, then the battery current is (battery voltage)/(circuit resistance). -- If you don't know or can't measure the circuit resistance, then the only way to determine the battery current is to measure it with your [milli]ammeter. Disconnect one of the wires from the battery, and insert the current meter right there, in series with…
When an ammeter is connected in a circuit which terminal of the battery must be connected to the positive terminal of the ammeter?
A battery and a light bulb are connected by wires in a simple circuit Where do the electrons that flow through the wire come from?
yes... this is possible if a diode i connected in reverse bias with a battery and a resistor for example. A diode in reverse bias means its anode will be connected to positive terminal of the battery and its cathode to the negative terminal of the battery. In such a case, minimal current flows through the circuit which can be neglected.
In resistive circuits,when you need the same current in the whole circuit,you use series circuit because in series circuit current remains the same.If you have two batteries of 12 volts each,and you need 24 volts you can arrange them in series to get 24 volts you have to connect them combine with opposite terminals.positive of one battery will connected with negative of other battery,and negative of second will connected with the first's battery positive terminal,they…
The current depends on what is connected to the battery's terminals. If nothing is connected to it, then there is no current, and the battery lasts quite a while. In general, the current is 1.5/resistance of the external circuit connected to the battery until that number gets too big, and then the voltage of the battery sags, because it can't deliver that much current.
A series circuit means a sequentially connected circuit, as opposed to a parallel circuit. To build a series circuit with a battery, a switch, and a light bulb, start with the battery... Connect one end of the battery to one end of the switch - connect the other end of the switch to one end of the bulb - connect the other end of the bulb to the other end of the battery When you…
The current in a circuit, expressed in milliamperes, is 1,000 x (battery or power supply voltage)/(resistance connected between the power supply terminals) If you increase the voltage of the battery or power supply, the current in the circuit increases proportionally, at least until something in the circuit gets hot, melts, fuses, and opens the circuit.
this depends on 1. whether the extra bulbs are being connected in parallel circuit or in series with each other, and 2. the power rating of the battery. supposing the battery power rating is greater than all the individual bulbs put together, the bulbs will glow the same maximum intensity if they are connected in parallel, and will become dimmer if connected end to end i.e in series.
The rating of "4600 mAh" is one description of the battery's capacity. It doesn't tell you anything about the delivery or discharge rate of the battery. Those depend on the external circuit that you have connected to the battery. For example, if nothing is connected to the battery's terminaks, then the battery is giving zero amperes.
