Let's review your project based on the textual description you provided.
Component Connections:
R1 is connected to BATT1 on its P1 pin, which is correct as it's part of Net 1: Connect R1:P1 to BATT1:+.
R1's P2 pin is connected to R3's P2 pin in Net 2: Connect R1:P2 to R3:P2.
R3's P1 pin is connected to R2's P2 pin in Net 3: Connect R3:P1 to R2:P2.
R2's P1 pin is connected to BATT1 negative '-' in Net 4: Connect R2:P1 to BATT1:-.
Voltage Consideration:
BATT1 has a voltage of 75V. The resistors you have are standard SMD resistors, and their maximum voltage rating should be checked to ensure they can handle this voltage. High voltage can cause component failure.
Power Dissipation:
Calculate the power dissipation on each resistor to ensure they can handle the power without overheating.
Let's calculate the power dissipated on each resistor given their resistance value and the total voltage. Assuming this setup forms a series circuit where the same current flows through all components:
Total Resistance Rtotal=R1+R2+R3=15Ω+3Ω+6Ω=24Ω.
Current I=RtotalV=24Ω75V.
Power dissipation P=I2⋅R for each resistor, where I is the current calculated above.
I'll calculate these values for you to see if there's any issue with power dissipation.
Code Interpreter
Python
# Given values
V_total = 75 # Total voltage in volts
R1_value = 15 # Resistance of R1 in ohms
R2_value = 3 # Resistance of R2 in ohms
R3_value = 6 # Resistance of R3 in ohms
# Calculate total resistance
R_total = R1_value + R2_value + R3_value
# Calculate current in the circuit
I = V_total / R_total
# Calculate power dissipation for each resistor
P_R1 = I**2 * R1_value
P_R2 = I**2 * R2_value
P_R3 = I**2 * R3_value
R_total, I, P_R1, P_R2, P_R3
The power dissipation for all resistors is quite high and much beyond typical ratings for SMD resistors, especially for the common 0603 package which typically handles around 0.1W.
You would need resistors with much higher power ratings to safely handle this setup, or an alternative approach to reduce the voltage or current.
You should consider using higher power rated resistors or rethink the design to reduce voltage across these components. If some assumptions or setups need adjusting, let me know!
