Confusion regarding electrical power

[nokia8650]

From P=(V^2)/R, it suggests that as you increase the resistance, you decrease the electrical power.

Conversely, from P= (I^2)R, it suggests taht if you increase the resistance, you increase the electrical power.

Please can someone explain the above.

Thanks a lot

Both of the presumptions are based on holding either V or I constant in determining power.

The real relationship is P = V * I.

R is a passive element that relates V and I.
