The formulas you are looking for is I = E/R.
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
The resistance of the load is what causes an electric current to flow in a circuit.
Power (watts) = current (amperes) * voltage (volts) Current (amperes) = voltage (volts)/resistance (ohms) 120 watts = current * 120 volts current = 1 ampere 1 ampere = 120 volts/resistance resistance = 120 ohms
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.
V = IR Voltage = Current * Resistance so 9 = 0.25 * R Hence R =36 Ohms
Resistance is Volts over Current 11 Ohm = 110Volt / 10 Amp
That depends on the resistance connected. Use Ohm's Law: V=IR. Solving for current: I = V/R. If nothing is connected, there will be no current (infinite resistance).
110volt
in voltmeter we have internal Resistance and connected in series , to current don't transfer in voltmeter , and we have internal resistance in ammeter and connected in parallel , to most current transfer through the ammeter.
Your current will be 30/R Amps. Where R is the resistance in Ohms.

:) It's connected together
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
I have no idea
An ammeter is connected in series. A voltmeter is connected in parallel. ammeter should always be connected in series instead of parallel becoz it is a low resistance device and we know that resistance is inversly proportional to current so more current will pass through it and if it is connected in parallel than it may get damaged
Current equals Voltage divided by Resistance. 9/2=4.5 amps.
because at start the motor draws larger quantity of current and this may affected the rotor windings in order to limit current always resistance is connected.
