How does increasing the number of cells in a parallel circuit affect the current?
by adding resistance in parallel more current is bound to flow
What happened when Volta connected the parts of his cells in circuit?
An electric current flowed around the circuit.
How does adding more cells in series affect the current?
Ohm's law (V = I*R) dictates that if voltage is increased, current must increase proportionately if the resistance stays the same.
When cells are connected in parallel then?
putting cells in series gives you a higher voltage but at the same current rating. putting cells in parallel gives you the same voltage but at a higher current rating. series parallel can give you both..
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
Why do materials like living cells heat up when electric current passes through them?
Living cells heat up when electric current passes through them due to the resistance of the cell's membrane, as well as the resistance of the internal cellular structures and ions. This resistance causes energy to be dissipated in the form of heat, leading to an increase in temperature.
What supplies energy in an electric current?
Electric cells
Why did Volta get an electric current when he connected the cells in a circuit?
Volta got an electric current when he connected the cells in a circuit because the cells produced a potential difference, or voltage, which created an electric field that allowed a flow of electrons to move through the circuit. This flow of electrons is what we call an electric current.
Can 2 cells push electric current harder round a circuit?
No, cells do not push electric current harder around a circuit. Electric current is driven by the voltage difference between the cells. Adding more cells in series increases the voltage, which can result in more current flowing through the circuit, but the cells themselves do not push the current harder.
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
What arrangement of three cells would result in the greatest electric current?
Connecting three cells in parallel would result in the greatest electric current, as this arrangement increases the overall current output. In parallel connection, the voltage remains the same while the current adds up, leading to a higher overall current output compared to series connection.
Why do solar cells need to lower resistance in the electrical circuits that make up their electronic system?
Reducing the resistance of solar cells increases the output current. Although the voltage remains the same the current is effected due to internal resistance. A reduction in output current can result in lesser diminished functioning in household appliances.
What process by which an electric current is produced?
An electric current is produced through a process called electromotive force (EMF), which can be generated by batteries, generators, or solar cells. When a circuit is closed, the EMF causes the flow of electric charge, resulting in an electric current.
How does increasing the number of cells in a parallel circuit affect the current?
by adding resistance in parallel more current is bound to flow
What are disadvantage of disco light?
An organism uses electric current in its nervous system . This electric current , produced by the brain are transported to certain nerve cells found all throughout the body .
