Why do electric cells have 2 terminals?
to form an electric circuit two terminals are required it is being closed and electric current passes through it .
What are the two things needed to make current flow in electricity?
A flow of electrons is needed to have a current. And there (usually) must be a complete circuit. And you need a voltage to make the current move around your circuit. All tied up in Ohms Law - which I'll leave to you.
What arrangement of three cells would result in the greatest electric current?
I haven't studied this for awhile, but... I assume by cell, you mean a voltage supply, like a battery. It depends on what else is in the circuit. If your circuit has a typical amount of resistance, then connecting the cells in series (as opposed to in parallel) will result in the largest voltage. Higher voltage means greater current across a resistor. However, if the resistance of the circuit is very low (like in a short circuit), then your batteries' own internal resistance may be the most significant factor, and batteries arranged in parallel may be able to sustain a higher current.
What is the principle reservoir for excess electric charge?
In common practice, the principle reservoir for electric charge is a battery. Fuel cells, which are like batteries except with external reactant sources, are becoming more widely used as electric reservoirs. In pure circuit design, the capacitor is used as the charge reservoir.
What is a cell in a circuit?
The function of a cell in an electrical circuit is to push the lectrons around the circuit. It can also be the source of charge in an electrical circuit.
What happened when Volta connected the parts of his cells in circuit?
An electric current flowed around the circuit.
Why do electric cells have 2 terminals?
to form an electric circuit two terminals are required it is being closed and electric current passes through it .
What happened when volta connected the parts of his cells in a circuit?
when he connected the parts he got an electric current.
Three electric cells each have a voltage of 1.3Vwhat is the total voltage of the three cells if the cells are connected in parallel?
voltage is still 1.3V in parallel circuit, voltage stays the same but current adds up in series circuit, voltage adds up but current stays the same
What supplies energy in an electric current?
Electric cells
What are two parts of an electric current?
cells and switch
What kind of cells are used to turn sunlight into electric current?
Photovoltaic cells.
What type of electric current is produced by fuel cells and solar cells?
ac
Do living cells have a high resistance to electric current?
yes
What kind of current is produced by dry cells?
Simply, direct current (DC). The amount of current depends on the circuit it is used in.
Are photovoltaic cells semiconductors?
Yes, that is how they convert sunlight to electric current
How do you get energy from the battery cells?
There is a chemical reaction in the battery cells with transfer of ion charges between the anode and cathode bringing about a charge differential potential between the cathode and anode.When connected by a conductor the flow of electrons in the circuit is the electric current energy.
