It's the same thing as in the other two questions.

Use these relations:

P = IV
V = IR

From here you'll end up with:

P = I^2V

Where I = current, V = voltage, P = power (Watts) and R = resistance.

Remember that 10 mins is 600 seconds.

As I recall, E = IR
where E = electromotive force (voltage)
I = current (amps)
R = resistance (ohms)

so 15/6 = 2.5 amps.

Not sure how much thermal energy that produces.

V=I*R
so I = V/R
in other words the current is 15/6 The answer will be in amps

If I'm remembering my school Science correctly, Power = I^2*R

so square the current (in amps) and then multiply by the resistance and you'll have instantaneous Power (in watts). Because they want the energy in 10 minutes, divide by 6 to get the answer in Wh (Watt-hours)

I can tell you the answer to the first one but not the second.

Current=Voltage/Total Resistance

Current=15 Volts/6 Ohms

Current=2.5 Amps

First, you can find the current using Ohm's law:
i=V/R.

Secondly, you find the resistive dissipation : P=V(square)/R
This give you an answer in W=J/s. You then multiply by the time in seconds to get the thermal energy.

currrent=voltage/resistance=2.5Amperes
energy in 10 min=energy in 600 seconds=power*time=voltage*current*time=22.5kilowatt

Use Ohm's law to find current.
V=IR
V=voltage
I=current
R=Resistance

To find the power use
P=IV
or
P=I²R
or
P=V²/R

Once you have power, use
P=E/t
P=power
E=energy
t=time

And that's it.
