AI Thread Summary
To calculate the current in each resistor, apply Kirchhoff's rules to analyze the circuit, focusing on the voltage and resistance values. The power supplied by each battery can be determined using the formula P = IV, where I is the current and V is the voltage of each battery. For the power dissipated in each resistor, use the formula P = I²R, where I is the current through the resistor and R is its resistance. The discussion emphasizes the importance of systematic analysis to solve for these electrical parameters. Understanding these calculations is crucial for effective circuit design and analysis.

Three batteries and four resistors are connected as shown above. Find (a) the current in each resistor,
(b)
the power supplied by each battery, and
(c) the power dissipated in each resistor.

how to calculate all of these?

Hi trans_pie! :smile:

Let's do (a) first.

What do Kirchhoff's rules give you for the currents in each of the two circuits? :smile:

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
