The 12V battery connected to the 2.4 Ohm combination will supply 12/2.4 or 5A. The individual currents will be 12/3 or 4A for the 3 Ohm resistor, and 12/12 or 1A for the 12 Ohm resistor. The 2.4 Ohm parallel combination is obtained from a simple product-over-the-sum calculation.

When a resistor is connected in parallel what happens to the size of current form the battery?
When a resistor is added the current goes down, that is expressed in the equation current= voltage/ resistance
In a simple circuit is a battery in series or parallel with the resistor?
In series.
What is the resistor of 18 ohms when connected to a 9v battery?
Even though it is connected to a 9 volt source, it is still a resistor.
Three identical bulbs are connected in parallel across a 12-V battery If one of the bulbs were removed from its socket then the potential difference measured across the empty socket would be?
12V. Every resistor in a parallel circuit shares the same voltage. It is the current that gets divided.
A red resistor draws more current than a blue resistor when they are connected to the same battery which resistor has the lower resistance?
The voltage of a battery goes as the current times the resistance (V=IR). Because the voltage is being held constant, the resistor that draws the most current will have the lower resistance.
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.

What is the resistor of 18 ohms when connected to a 9v battery?
Even though it is connected to a 9 volt source, it is still a resistor.
In which case will there be more current in each of three lamps- if they are connected to the same battery in series or in parallel?
more current will be in case of parallel because in series combination resistence is greater with respect to parallel combination
A coil of 8 ohm parallel with coil of 20 ohm This is connected in series with 12 ohm resistor If the whole circuit is connected across a battery having emf of 30V internal resistance of 2ohm whats v?
v of what? v across what? v measured from what 2 points? v across the coils? v across the resistor? v across the coils and resistor? v across the battery? v across the battery and coils? v across the battery and resistor? or are you asking what v stands for? v stands for voltage.
What is a battery discharge tester?
It is a meter with a high wattage resistor connected parallel with the meter that drains power from the battery while it is measuring the voltage it is used to test the condition of the battery if the condition is good there will not be a large voltage drop while testing the battery
What would be a basic electical circuit?
a battery and a resistor connected together.
How far can the electric current of a Duracell battery travel through a long crocodile clip?
All the way along when the crocodile clip is connected to a resistor, when the other end of the resistor is connected to the other side of the battery.
What battery combination will operate a toy?
