If you are talking about batteries of different physical sizes but of the same voltage then the answer is yes. The light bulb requires a specific voltage to operate. As long as the batteries add up to the voltage that the bulb requires, the lamp will light properly. Larger batteries usually have a greater operational capacity. The load being of equal amperage draw, the D cell load will operate longer than a AAA cell load.
When batteries are connected in parallel, the total voltage remains the same as the voltage of a single battery.
the voltage is the same 12v (some have more amps) and the terminals are all the same size - but the battery cases are all different sizes. if the battery physically fits in the battery pan (holder) and the hood closes - its safe to use.
The voltage remains the same.
this question is missing information and therefor makes no sense
Cars all have different requirements and specifications and this includes the battery. There are both top and side post batteries in a number of sizes and amps.
If the batteries have EXACTLY the same voltage, then nothing will happen, because there will be no voltage drop in the circuit, and hence no current. If the batteries have SLIGHTLY different voltages, then there will be a voltage drop in the circuit. Since there is low resistance, there might be high current, causing damage and/or an explosion. In all probability, however, there is enough internal resistance in the batteries to simply cause them to equalize in voltage.
When connecting batteries in parallel, the total voltage output remains the same as the voltage of a single battery.
You will get double the voltage.
Assuming all of the individual batteries are the same voltage, if arranged in a parallel circuit the voltage is the same as any one battery. If arranged in a series circuit the voltage will be the sum (the total) of all of the batteries added together.
The batteries can be connected in parallel or in series. In parallel, good batteries of the same voltage will have a total voltage across them equal to the voltage across one of them. Those batteries in series will have a total voltage equal to the sum of the voltage of each of the batteries.
Connecting batteries in parallel does not affect the overall voltage output. The voltage output remains the same as the voltage of a single battery.
