Answer:
1. Parallel circuit
2. Parallel circuit
3. Series circuit
4. Series circuit
5. Parallel circuit
6. Parallel circuit
Explanation:
1. In a parallel circuit, there are multiple paths for current to flow. The path each current takes depends on the resistance of the resistors on that path.
2. In a parallel circuit, current splits up into various paths to get the total current through the circuit, the current flow through each resistor is added.
3. In a series circuit the voltage across each resistor is not the same. to get back the total voltage, the voltages across each resistor needs to be added.
4. Series circuits have voltage drops across each resistor. this makes the voltage across each resistor depend on the resistance of the resistor.
5. In parallel circuits voltage is the same across each resistor because they are all connected directly to the same source.
6. In parallel circuits, the power is the same in each resistor of equal resistance since the voltage across each resistor is the same

Answer:
the rate of heat loss from the steam turbine is Q = 200 kW
Explanation:
From the first law of thermodynamics applied to open systems
Q-W₀ = F*(ΔH + ΔK + ΔV)
where
Q= heat loss
W₀= power generated by the turbine
F= mass flow
ΔH = enthalpy change
ΔK = kinetic energy change
ΔV = potencial energy change
If we neglect the changes in potential and kinetic energy compared with the change in enthalpy , then
Q-W₀ = F*ΔH
Q = F*ΔH+ W₀
replacing values
Q = F*ΔH+ W₀ = 420 kg/min * (-600 kJ/kg) * 1 min/60 s * 1 MW/1000 kW + 4 MW = -0.2 MW = -200 kW (negative sign comes from outflow of energy)
