The two resistors in series have an effective resistance given by the formula
Reff = R1 + R2
therefore
Reff = 30 + 30 = 60 ohms
V = IReff
I = 40/60 = 2/3 (or 0.67) A
If 3 identical 45-ohm resistors are connected in parallel, the net effective resistance of the bunch ...and the load seen by the battery ... is 15 ohms. The current supplied by the battery is60/15 = 4 Amperes.(This assumes that the battery is capable of supplying 4 amps at 60 volts, or 240 watts !)
1.5 ohms. Two 3 ohm resistors in parallel.
4 resistors were connected in parallel it yields 5A of current from 220V supply.
You need to calculate the equivalent resistance. For instance, if the three resistors are connected in series, simply add all the resistance values up. Then, you calculate the current (in amperes) using Ohm's Law (V=IR); that is, you need to divide the voltage by the resistance.
The equivalent resistance of multiple resistors connected in series is the sum of theindividual resistances.(10 + 60 + 50) = 120 ohms for this particular trio of resistors in series.It makes no difference what battery they may be connected to, or if they're connected toany power supply at all.

Resistors are wired in series when they are connected in a line. The current flows through the resistors one after the other.
The resistors connected in single path are called series resistances or resistances in series.The current across both the resistors is same while the potential differences are different.
1.5 ohms. Two 3 ohm resistors in parallel.
"Amp" is not a specification associated with resistors. It could be anything.
if resistors connected in series the resistance will increase.Then it limit the flow of current through it. voltage may be increased. A: by connecting any resistors in series it will limit the current flow it will effect the current but never the voltage applied
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.
If the resistors are connected in series, the total resistance will be the sum of the resistances of each resistor, and the current flow will be the same thru all of them. if the resistors are connected in parallel, then the current thru each resistor would depend on the resistance of that resistor, the total resistance would be the inverse of the sum of the inverses of the resistance of each resistor. Total current would depend on the voltage and the total resistance
